[sdiy] saw vs ramp, audible?

[Donald Tillman]

Note that a sawtooth ramping down has all the harmonics in phase with the fundamental.

And a sawtooth ramping up has its harmonics alternating in phase (+1, -1/2, +1/3, -1/4,...) from the fundamental.

So when you want to combine a sawtooth with, say, a square wave, one will make an awful lot more intuitive sense than the other.  This is extremely important to people, like myself, who combine waveforms a lot.  

Terminology complaint: I don't think the word "sawtooth" is defined to be exclusively ramp up.  Nor should it be, given the above.

I have believed for years that the difference is not audible, that maximum disconinuity followed by minimum discontinuity is what a saw or ramp is, and inverted but otherwise identical waveforms sound identical. I came across a wealth of traffic online today arguing against that. I'm super skeptical. Folks' arguments were passionate but not complete in a way that could convince me. What is the real deal here?
