SPOILER: He doesn't get it.
But that's not why these clips are important. They are vital for another reason.
You see, Steven has never managed to complete this weight before. And while he is constantly adjusting and improving his form in order to eventually get it, in the end it is his dedication and refusal to give up will be what will make or break a conquest of the weight.
That is why these clips are important. Not as an example of perfect technique or amazing accomplishment. But as proof of a key factor: not giving up.
Being defeated is worse than a moment of failure. And no matter how many times he fails, Steven will not be defeated.
It is this attitude that will eventually produce his victories.
