Elaborate please, and dumb it down a bit too.
I'll try. Jitter is a periodic *variation* in the timing - just like wow & flutter on a vinyl LP. The variation in timing causes modulation components (the jitter spectrum we can measure). A fixed staggering doesn't vary with time - it just causes a slight, steady delay. In a way, the modulating frequency is 0, so there are no intermodulation results.
