The CIS is dumb, of course. Maybe Danny was worried he'd kill Luke, or something. Anyway...looking at the feats.
So we have one hit where Luke is more-or-less fine after, and another hit where Luke...
*checks*
Dude, that doesn't drop Luke hard. It's a super-powerful strike that accomplishes LESS than what the 'booong' hit did.
He punches Luke in the face. Luke goes flying, because the Iron Fist Hits Hard™. Luke hits the wall and falls from that impact (he's sideways, in the air, of course he falls down).
Luke then immediately starts to get up.
Does he perfectly pop back up to his feet? No. But there is only a brief wobble when he's on all fours, and then he's just continuing to get back up again. Then everyone stops to look at the cops. Luke finishes getting up. Danny kind of 'oh ****'s and runs. And Luke walks off himself.
It's a perfect punch in the jaw, where the other hit was to the center of Luke's chest, and it still accomplishes no more than making Luke wobble a little when he's getting back up from where the impact flung him. At least the other punch has Luke wincing and not immediately getting up.
Between that and the truck feat, and Danny not really showing the capacity to throw Iron Fist after Iron Fist (as I recall, could be wrong, but mostly they were one-shot fight-enders kind of thing), I really don't think he's putting Luke down.
