Trail braking vs conventional corners

[OldSchool]

First off trail braking is used in Dirt biking, Motocross, Adventure off road riding.
Not so much in just "track" riding. It is used as a slow hairpin turn maneuver for manipulating man and machine around very tight almost reversed corners in off road conditions and normally does not apply to street machines. However like many things the technique or parts of it anyway can be applied to street riding. Personally I feel it is total overkill for street riding. We use a watered down version for making u turns on our big bikes. Any further than that is unnecessary. Sounds more like an instructor was trying to impress a group of students on his knowledge more than teaching practical application.
