Outdated comments in AssignTransactionId?

The AssignTransactionId has the following comments:

        /*
         * ensure this test matches similar one in
         * RecoverPreparedTransactions()
         */
        if (nUnreportedXids >= PGPROC_MAX_CACHED_SUBXIDS ||
            log_unknown_top)
        {
            ...
        }

However, RecoverPreparedTransactions removes this reference in 49e9281549.
Attached remove this reference in AssignTransactionId.
