It has always been the executor in my mind the shot of the bridge... But in terms of the sequence of events I can't argue that what is being said actually does make more sense in terms of narrative and Shadow is the first sniff of the executor we should get.

So even though my mind has always said that this is the executor it might actually be better to treat it as someone said a "Goof"

I do honestly think there is a minor difference in the Bridge model still though with the radar bar is smaller and is not the angle.

It does not make sense but then again a lot of things don't make sense that is what we are doing here after all.... To make Empire Strikes back make complete sense so it's fair game.
