Unfortunately, I can't seem to come up with anything more clever.

Basically, when you are broadcasting outside the server, you are
broadcasting SQL queries, and those queries do not have information
about non-deterministic functions and have issues with universal commits
on all node.

Ahh..I like this explanation, because the inter-server communication in clustering is not necessarily SQL queries.
