I've ridden one where pedalling got the currently selected level of assistance, but pushing a lever temporarily increased the level (as long as it wasn't already on the maximum) more and more until you reached the max. I don't remember the brand. They called it simply a lever, but I expect some would call that a throttle.
Yes, that is a throttle.
Anything which you control which alters the amount of power output is a throttle.
