What is the reasoning behind that recommendation?
To allow headroom in your mixes, giving you the ability to add more tracks, process those tracks, etc., without digital clipping. If the volume is too low, that is what your amp/speakers are for. You have to remember that most professional studios don't have the tools or equipment to Master their recordings (wikipedia Mastering to learn what that is if you don't). When stems are sent to mastering houses, they expect the mix to have AT LEAST 6 db of headroom to allow them to polish and finish your song. Multi-band compression, EQ, reverb, and exciters/maximizers are common tools for the mastering engineer-- all of these things raise the level and apparent loudness of the audio... headroom is needed to avoid digital clipping. Digital clipping is one of only a few disadvantages of digital audio (versus tape) since it sounds like DEATH as opposed to nice harmonic distortion...
Imagine I've already sequenced and recorded 16 tracks into my DAW of choice: 8 tracks for drums and 8 tracks for vox, bass, guitar, keys, whatever. If all of those individual tracks are peaking towards the red (0 dbm), I am now unable to apply certain plugins to those tracks without that nasty digital clipping or (and more commonly in today's world) overuse of limiters which can create artifacts (unnatural sounding compression that changes the way your entire mix sounds).
examples:
1) Say my sample was recorded at a high level into my DAW (with peaks up around 0dbs). I feel as though the sample itself sounds dull/lifeless and I want it crisp and cutting through the mix. I might apply a "maximizer" type plugin to accentuate the sample; doing this will raise the signal level (and apparent loudness) of the sample, but oh shite, there is no room for this extra volume since you failed to record with any headroom whatsoever. Maybe you add a brickwall limiter to prevent clipping but oh shite, now your sample has that "pumping" digital sound to it and is nothing like what you intended it to sound like.
2) I am crafting a hip-hop beat on my MPC and i'm preparing to record it into my daw as several different tracks (kick on 1, snare on 2, hats on 3, etc, etc.). I hear a great mix coming through my speakers after setting the levels of each track in the MPC.
------->If I record my beat into the DAW at proper levels (under -10 db), I now have the headroom NEEDED to have an MC/singer, whatever, come in and voice the beat, and then mix the vocal in with the rest of the song. After I've done that, I find that the vocalist's voice really covers up the sound of my snare or toms. No problem! I have the headroom needed to thicken up the sound of the snare using some compression, EQ, whatever else... (which raises its volume).
------->If I had recorded my tracks to where the levels were peaking, not only would I be unable to apply certain plugins to my tracks (compression and make-up gain, effects, whatever), I will be unable to fit the vocal into the mix without totally re-working it and likely changing the character of the music in the process.
Lots of bedroom producers (especially in this new EDM thing) will just throw brick-wall limiters on each track... that's fine if you don't want your music to have any dynamic range (and if you enjoy headaches within minutes of listening on closed back headphones).
Engineers give the musician/producer as many options as possible when recording--- knowing they will want to add remove, adjust certain things later, or totally remix the song!
I would wiki/google/forums and read-up on compression, compression vs. limiting, post-processing/mastering, and especially dynamic range.
I saved this to my bookmarks years ago... it's a nice article about loudness, dynamic range, and how these things have changed as technology evolved from tape to CD:
