I think I know what your talking about. The computer Superjump-Cancels the c.MP, so it’s like
c.lp, c.mp, SJ-cancel into air dash, down-hk (diving kick) (crossup) thats a reset right there, and pretty much 99% of the time, players do NOT expect that. they expect you to special, air combo, or whatever.
to make it even more damaging (not a reset though), with tron you can
c.lp, c.mp+tron proj, SJ-cancel into airdash, down-hk (diving kick) (crossup) and do whatever from there… special, air combo, whatever. Hope that helps!
