fix: correctly inform when stopped by visitor

This method was not correctly informing whether it was stopped by the
visitor. If there were more entries buffered that were not yet expired
then it should not continue. In that case it would also say that it was
stopped by visitor, but that's incorrect.

This rectifies that behavior.
