Why do multiple downstream channels matter?
I normally have four downstream channels and three upstream. I'm on the Blast level and my speeeds tend to be 56-57 down and 11 up.
From time to time, when I look at my modem settings (6120) I seem to have lost one of the downstream channels. This happens quietly - never any entries in the modem log, just "poof" it isn't there. This morning was one of those days -- I had four, now I have three.
I did a speed test. Same as usual -- 57/10-11. Then I rebooted the modem (which seems to be the only way to get all 4 back). Then checked the speed again. Also 57/10.
1) why do I lose a channel, and why isn't the Motorola showing it in the log?
2) Is this more likely to be a modem issue (my modem) or something at the head end?
3) If the loss of a channel doesn't affect my speeds, why is having multiple channels so important?
3) redundancy, when 1 or more channels go out of range/get busy your modem and the head end agree to shift to one of the working channels.
As you've noticed this is a seamless transition, really unnoticeable at your end, and even if you never reboot the missing channel or another one may eventually take it's place.
No need to reboot or be obsessed over the logs and signals pages when it's working so well, just enjoy it.

Redundancy is good. Be glad that you don't have 1 down/up channel like some of us had to have on the SMC8014. I had drops for 4 months and 10 visits before a tech guessed to try a multi-channel modem.
