IME it's not so much that the literal digits 9, 1, 1 are pulse dialed, but some switches are configured so that a bunch of repeated on/off hook sequences will be treated as an emergency call. I think the idea is, if someone is severely incapacitated, their attempts to pick up the phone will be noticed and acted upon.
