Much more important question is, why didn't he ask you to go-around, if he felt you were outside parameters??
Below 200 feet, you shouldn't follow any landing aids anymore (including PAPI), instead fixing the aim point in the windscreen and keeping it there until flaring. Which is what it sound like you did.
You don't specify your type. But dipping below the "visual profile", it NOT recommended by Boeing! Changing you profile in the last few hundred feet, may lead to a messed up flare and a long landing. Landing performance takes normal profile and flare into account, so it's not necessary at all.
From what you describe, it seems like you did it right. And if you didn't, the question remains why the captain in question didn't order a go-around.
