It may have been a red Herring, but it's also noteworthy that both Puzder and TrumpCare were pulled, not actually voted on. I will need republicans to formally vote down something Trump wants before I believe they're willing to oppose him in large numbers.
Problem with that is that the party leadership is capable of counting votes before the vote is held, and will not bother holding a vote if something is going to lose, as we saw in the cases mentioned above. So unless Democrats are going to start siding with Trump on certain issues, then on any vote for which more than a couple of Republicans are going to defect, there just won't be a vote held at all.
Indeed, it is hilarious in a sense. The party leadership wants to avoid a situation where the rank and file rebels against them and works to prevent that scenario. On the other hand, Wulfric demands that the rank and file rebels against them to prove that they are capable of independent action. As it happens, the party leadership is working (coincidentally of course) to ensure that Wulfric will never consider the rank and file as being capable of independent action.
