Sorry, but I don't like this wording. The problem is that the comparison has two row sets --- the left-hand side, and the right-hand side.
Huh...the left hand side must be a non-set scalar or row constructor.
Each row on the left-hand side is compared with the row set on the right. I also don't like people thinking about the result of ANY since it is really <comparison> ANY that is being used.
Then there is some more rewording to be done since: "The result of ANY is “true” if any true result is obtained." (v10; 9.22.4)
Maybe:
The result of ANY is “true” if the comparison returns true for any subquery row; otherwise the result is “false” (or NULL if any of the comparisons result in unknown)
