Yes, I think this is something that Gor was looking into as a wording issue
that could do with some clarification.

I think the suggestion was something along the lines of adding some wording to
ensure that the evaluation of a an await-expression was sequenced atomically
with respect to the evaluation of other expressions in the statement.
