Harry’s commitment is quite weaksauce, and it was surprising that he wasn’t called on it:
I sshall help you obtain the Sstone (...) sshall not do anything I think will annoy you to no good end. Sshall call no help if I expect them to be killed by you or for hosstagess to die.
So he’s free to call help as long as he expects to win the ensuing encounter. After which he could hand the Stone to a subdued Quirrell for just a moment, technically fulfilling that clause as well. Also, the “to no good end” qualifier? “Winning against Voldemort” certainly would count as a good end, cancelling that part as well.
Parseltongue doesn’t produce binding promises. There no need to technically fulfill clauses. It doesn’t function as a commitment device. It just makes someone talk frankly about his own intentions.
Harry can’t provide any stronger commitment and is indeed sorry about his inability to provide a stronger commitment.
