Probably not.
But, they may know about long path, just about everyone who plays around on HF hears about it soon after getting on HF. SO, one could assume that people who are part of a DXpedetion have enough experience to know about propagation to different parts of the world as the world turns.
Take heart. If you don't work them this time, you have the excitement of trying to work the station from E4.
