That's not the case at all; it is just describing the same waveform twice. 
The defining difference is the nature of the transition being linear or 
exponential, as per my original email.

It would be interesting to note the harmonic structure of either. I don't 
know enough about Fourier to be able to analyse it myself; however, it is 
still the case that they wil be different but whether the *audible* 
difference is noteworthy remains to be seen!

Agreed, as an LFO the linear ramp and the exponential saw would sound 
different (as a modulating source).
