Are you allowed to ask another player which way something rounds?
Yes.
There is no need to involve the host in such questioning.
However, I do take issue with the way you've phrased your question. I ask that questions (or answers for that matter) don't refer to anything the host says outside of official mod posts, such as votecounts.
For example:
Instead of asking "Can you paraphrase how the host said this?"
Ask "How does this part of your role work?"
Instead of saying "The host said it rounds this way."
Say "It rounds this way."
