That is one that is misleading... It could of course be a roundabout hall so in effect Lobot spotted them went and got the troopers and came around the other side...To spring their arrest.

Except if you notice in the shot with the SE windows (which Ady is keeping and even fixed in that "arrest" shot), there is no roundabout hall - you see the outside and towers. True, we could remove the SE windows and then that'd leave that possibility of a roundabout, but honestly I wouldn't prefer that over either of the other two suggestions I already mentioned.

Star Wars can be interpreted in so many different ways it can appear muddled when it is in fact not but on the flip side of this it can appear to be fine when it is in fact muddled.

Btw, I really like this quote as it is very true. I think this is one of those times. To me, this sequence appears fine as it is when it is in fact muddled.

Imho, I think the best approach for improving this sequence is only flip Lobot during the arrest so he's coming from the left instead of the right (but if it's easier for Ady to do, the Stormtroopers could be flipped with him too), as this change will be the least noticeable (Ady has no problem flipping shots for correcting other minor things after all). I'm curious what Ady thinks.
