Never mind about legality, if you pass a line of cars on the right and get in front of the lead car going straight- that's just going to pi$$ off all those drivers that just passed you when they have to RE-PASS you.

I wouldn't ever do it just for that reason. I just get in line behind the cars and go through the intersection like a car.
I think that was poor advice, for sure.

Never seen a bike box, but I still don't know that I'd do it...
