Well, it sort of should happen, what with the superposition of the peaks and troughs of the soundwaves and all.

Hmm, well it seems like V01 and V03 should potentially cancel each-other out, but I didn't think they would be phased that way on reset. I've always understood the waveforms to be:
So what I'd expect if their phases are reset when adding V01 and V03 you'd get:
MIX: HHHHMMMMMMMMLLLL
But maybe in Famitracker V03 is:
V03: LLLLHHHHHHHHHHHH
MIX: MMMMMMMMMMMMMMMM
This would sound the same except in cases where the phase is important, like the example you've just posted.
In general though, it's probably best to avoid counting on phase; don't write the same note in S1 and S2.
This has been discussed before; I think jsr said you can reset the phase of a square channel by crossing some frequency (I forget which one) but otherwise there's not really a way to do it? Also, you have to have an NSF player that's going to obey that minor quirk as well. It would be iffy at best.
i think you can somewhat rely on it, but you can't be overly specific. if you use P81 on one channel for instance, nearly all NES players are going to play back the two waves with a small amount of phasing. the speed/duration/intensity of the effect would vary a bit though.
Doubling with P81 produces a phasing effect, but you're not relying on a specific phase, just on a continual phase change, so it is fairly robust across different NSF players.
When you play two at the same pitch, though, you can't reliably determine what phase it's going to start on. For instance, you may notice that if you make an NSF of Mex's example, it'll sound different in other players than in Famitracker. You can get double volume, silence, or any phase mixture in between.
rainwarrior: That's correct, V03 is an inverted version of V01:
V01: HHHHLLLLLLLLLLLL
V03: LLLLHHHHHHHHHHHH
so using this setting and resetting the phase on both channels will cause silence.
The phase reset quirk has been known for a while and seems to be present in all NSF players that I've tried, so that's usually not a problem. But it's not a good idea to rely on absolute phase since it's dependent on register update timing and might vary among different versions, and in particular between the tracker and when exported.
