My poor understanding about some sentence in scheduling.md

Could you let me know whether I understand this sentence correctly.

Note how every time a frame is scheduled, we set up a timer to schedule the next one. -> Note that when schedule_animation_frame is called, we set up a timer to schedule the next render.

As a non-native English reader, I am confused by the two uses of the verb 'schedule.'

Actually I think this is an error in the book. The code later in the chapter is correct, but this one is not quite correct, because schedule_animation_frame is called in the main event loop constantly and the timer scheduling is not throttled.

I'm making a PR now to fix it, thanks for reporting.
