Wow Souk,
Did he actually pull the E brake? If one of our instructors ever actually did that in a student’s car, our head instructor would pummel him (well, talk to them sternly and suspend their instructor privilege for a while).
I have heard people say to do that in a tight hairpin, but from my experience it is about 1.5 seconds slower if you do that. It takes more time to get the car settled back in after such an abrupt suspension unload. It is better to go real late into the turn, start your turn and then get back on the gas early to come out under full power.
