Yes. You don't get to be selective about what to keep: it's everything
up to a certain time instant, and nothing after that. Stopping by XID
is just a different way of identifying what that time instant is.
BTW, stopping "before" an XID actually means stopping just before its
commit or abort record, so transactions that ended before it did will
be included in the recovery.
