Confusing comment in TransactionIdIsInProgress

Shouldn't the comment read "If first time through"?
/* * If not first time through, get workspace to remember main XIDs in. We * malloc it permanently to avoid repeated
palloc/pfreeoverhead. */if (xids == NULL){
 
...    xids = (TransactionId *) malloc(maxxids * sizeof(TransactionId));
