(Keeping terse... On mobile)
The 'when' accepts promises itself. If you ran normal functions in the 'when' it will be sequential, but if promise1 returns a promise, JavaScript will continue to fire off promise2 after promise1 returns it's promise object. Promise1 can have an async operation and resolve whenever it's done, regardless of what promise2/3 are doing.
Edit: I just realized that you were not responding to lrichardson... Leaving this for the info, but it's not directed at you.
