Legal Question in Real Estate Law in California

Probably; that puts a little more pressure on the buyers and is fairly standard practice. You may also want to try a round of face-to-face negotiations with the buyer and your agent and the buyer's agent as well, to clarify your intentions regarding moving. Negotiation and discussion of issues may calm the buyer's jitters about being able to move in promptly. Kinda odd that they would be concerned about immediate occupancy when they are making the closing date uncertain by their own actions (or inactions). You could also ask the broker that your agent works for, for his or her professional opintion. I think everyone here needs to understand what the other perty's concerns are.

Answering your question accurately is going to depend on the purchase and sale agreement, and any escrow instructions, especially with respect to whether any provision was made for you to occupy the property until close of escrow.
