While it's true that Palpatine can be caught off guard, it's also true that Maul is a FAR cry from Yoda.
Anyway, the impression I got from the scene is that Maul was pinning/holding Palpatine against his will, and Palpatine resorted to force-dropping the ceiling fixture toward Maul in order to make him lose focus so that he could break free. If true, it would mean that Maul momentarily overpowered Palpatine with the Force... In which case I can understand why the scene was cut/deleted.
During the episode itself, Filoni went out of his way to show us that the Brothers weren't even remotely close to Palpatine's level... Especially with the Force. He toyed with them effortlessly in that area. That said, including the scene in question would have somewhat undermined the the tone of the entire battle(ergo it getting snipped.)
Furthermore, it's still a deleted scene that, judging by the rudimentary graphics, barely made it past the pre-production phase--so we know it was cut VERY early. No way in hell it should be regarded as canon, imo.
