Not necessarily, if the token is tied to your public key, but it's a trade off, you need to trust the payer and the mint. Everything is a trade-off

Yes, that's indeed the standard protocol. The receiver immediately swaps the token against a new one with the mint.

The alternative flow is to lock a token to your pubkey and send it to you. Then, nobody can spend it except you so it can't be double-spent.
