I can confirm that Adywan is correct (the sheet music indicates this overlap)

The first note of the piano riff lines up exactly with the foot coming down and the double time transition to the Hanger.

I have exactly the same rhythm as what is displayed in the youtube clip as in the beats are exactly the same except when you observe the change to double time at the correct point and take into account the pause you get this result.

Why would they not record it as one whole piece of music with the piano riff as you have displayed it in the youtube clip then if there was not meant to be a pause?

That is the real big question on this and it's not about calling right or wrong but It just don't feel right I am sorry. The only possible excuse I can give for excising the first few bars of the piano riff are that they were a lead in specifically for the percussionists and were played in mind of them being edited out. As the percussion in this part is actually very complicated. Agree or disagree with me or agree or disagree with the actual recordings and sheet music too we have been given. The whole thing that has me in disagreement about this particular clip is that the pause works so incredibly well and it was how it was recorded, so this is what really has me scratching my head about that particular point.

And the change to double time at the end of the R2-D2 scene rather than it actually changing to double time when we actually transition to the very busy hanger. The Hanger shots are all quick cuts specifically cut that way to be in double time to match the music the R2-D2 scene is not.

You have my final take on it, If you disagree with it I don't have a problem with that.
