My guess is:
The F-22 has a power/weight ratio about 10% better than the F-15 or F-16, which was probably the pilot's previous aircraft.
He shoved the throttles forward to what felt like mil power on his previous jet, judged by the feeling of acceleration. This, however, would be less than mil on the F-22.
Everything else follows.
Somatogravic illusion may also be involved.
