Exactly. You'd need to use Test and Go (that's the name for the 1 night quarantine scheme) into Bangkok, and when released from that you are free to fly on to Phuket.
You could also use Test and Go into Phuket, but to do that you have to fly directly there on an international flight from outside Thailand (i.e. no connecting in Bangkok).
