Wrong and wrong.
This is the point at which the contact patch is just barely sliding a little. It's not sliding much, so you still have control. This represents maximum traction for most tires and is the reason Bob Bondurant says "a squealing tire is a happy tire."
And many cars drop the AC clutch solenoid at WOT (so it won't really do anything when you want to go fast). And even if the car doesn't, you wont lose 10% of your power, and peak power doesn't matter in a real curve anyway.
