I think it has to do with gain produced by the Q control. The 
regeneration produces gain which can lead to clipping.

There is sort of a philisophical note about distortion. Any change 
to the input waveform can be considered distortion. So a filter 
produces distortion by changing the waveform. For obscure 
mathematical reasons, this is not called distortion. Typically in 
engineering, distortion is refered to as any effect produced by 
"non-linearity" which is when the output does not relate precisely 
to the input using the equation x = by+a (which is the classic 
"slope offset" formula from algebra).

Non-linear distortion is used to "bend" the straight line sawtooth 
wave in the Waveform City into all those other waveforms. The 
waveshaper can process any signal, and running the output of 
the Omni Filter through the waveshaper is how you get those 
TB-303 "squonk" noises you hear on the Nike commercials.
