Treehouse TeacherThere are two reasons a while loop will exit. Either the condition to be evaluated becomes false, or a break statement is encountered. In his example, he's intentionally setting up an infinite loop so that it will continually ask the user what they want to do. Do they want to list the products or add a product etc. But when the user types "quit", the break statement will execute causing the while loop to exit.

He briefly explains this at 3:56 in the video
Hope this helps!

Treehouse TeacherThe only difference there would be that the block of code inside the do would be guaranteed to run once. The while(true) would still be the condition to evaluate at the bottom.
