I dont think you could corner tight enough at a fast enough speed for the fluid to rush to one side of the cylinder and air to get in. And if you did take a video next time lol.
You could have a very tiny leak somewhere in the system, that only lets fluid out slowly under high pressures. eg when you hammer the pedal. But this would be a gradual pedal change.
Its a tricky one.
If you leave the cap off the master cylinder like they did it is quite easy to get the cylinder to suck air. Once you lose half the fluid it will pick up air in a corner easily.
I would still check the whole system.
