Actually, here is a different thought that I found on TV tropes and actually makes sense: Bill never actually agreed to help Dipper. The dialog up was something like this:

"I CAN help you."

"You CAN?"

"Yes. Give me a puppet."

"OK sure."

He said he COULD help him; he never actually said he would.
