Sidenote: it goes to a wide shot after he pours water on himself. The 2 ladies react to this bizzare behavior with one making a phonecall to someone about it.

Someone pointed out - He pours water into his glass and drinks it like a normal person at the end of his speech.
So it definitely seems scripted. Link for him drinking normally here:
