It's neither of these,
https://fedoraproject.org/wiki/How_to_create_and_use_Live_USB#Data_persistence

'currently implemented (as a Device-mapper copy-on-write snapshot),
every single change to it (writes AND deletes) subtracts from its free
space, so it will eventually be "used up"'

This is not the same as choosing to create a live image with an
accompanying filesystem on a USB key, where the extra mounted
filesystem is an ext4 or similar. But system files in a live image are
located in the squashfs and are subject to the overlay limits.
