What do you think will happen when the apparent wind is abeam? If the leeward sail is sitting in turbulent air then the weather sail must be stalled. Sails are airfoils and airflow around them should be laminar on most points of sail. Even if flow is disconnecting from the weather sail a little bit, that dirty air moves aft as the boat moves forward at its ridiculous speed.

However I would expect the apparent wind on the leeward sail to be higher than on the weather sail, at least as you get close to wind abeam. That would be fun to see.
