It's not just about restoring a line of dialogue. That shot interrupts the flow of the film and is wholly unnecessary.

I completely agree with you on the 2 shots where you see Vader's shuttle fly towards the Executor, and then again when docking in the Executor - those SE shots are wholly unnecessary... but I do not see how the 1st SE side-view platform shot interrupts any flow, this shot has a lot of worthwhile potential (such as what I just described) instead of being discarded completely.
