No.your saying if he doesn't cancel the Nomad Dash into block?
1- If he cancels F4 into ND and you're blocking, he's at -5. Kung Lao's spin is 6 frames, so you won't be able to punish him.
2- However, you can spin right after his F4 (if you block it), BEFORE he can ND (meaning even if he inputs it, you can spin him), because there's a 6 frame gap. So you're spinning BETWEEN F4 and ND (so the ND is never fully performed).
In the first scenario, he was able to perform F4 into NDC. In the second scenario, you spun him out of it, before he can ND. I don't know how else to simplify it.
If you still don't get it, go to Somberness' thread where he explains frame data (you seem to be confusing block advantage with cancel advantage, and therefore, gaps). Then go to the Kabal forum, read his frame data, and read the guide made by Master D where he explains the gaps in all of his strings and how they work.
EDIT: Luzlou has a pretty cool guide on Kabal's gaps.
