Do you think with this words it's clear that the new transaction uses
the same snapshot used in <N>, instead of incorrectly saying that it
will use <N> as the snapshot for the new transaction?

Thinking in these terms, I'm more inclined to adapt (renaming SHARING to
SHARED) Vlad's syntax to:

SET TRANSACTION ISOLATION LEVEL SNAPSHOT SHARED FROM <N>
