Beats me, saw it in a macro once, added it into my Faerie Fire click macro and it fires it the first time, then never again until the reset condition happens on the castsequence. Not sure if that means it's a reserved word or if it's just jamming up my macro in a very pleasing and expected way...

No. The point of the commas is timing. For a spell like Insect Swarm, you want it to reapply every time it is dropped {or better, every time it is about to drop}. Combat and target are acceptable reset conditions, but /click is still performing actions on that sequence, even if it is not actually doing anything, so that castsequence will not have 12 seconds of inactivity.
Ahh, right, I forgot that whole "inactivity of the macro, not a cooldown timer" bit. Oh how sweet would it be if it was a "timer since macro started" thing.
