Exit full screen for both windows upon leaving split view

Question

In split view, when I exit full screen with one window (by clicking on the top left green button), the other windows remains in full screen and is hidden. What is the way to exit full screen for both windows at the same time?

Answer 1

Yes. Open Mission Control and hover over the space with the two windows until you see this
.
Clicking the white circle will minimize both windows and drop them to whichever desktop they started out on.

Answer 2

It seems from the apple support article https://support.apple.com/en-us/HT204948 there is no way to do this:

The other window remains in full-screen view. You can switch to it with Mission Control, or use a Multi-Touch gesture such as swiping left or right with four fingers on your trackpad.
