It is a common assumption it does, but I have seen time and again applications either coredumping and hanging while doing so or just getting terribly confused when their presumed current directory disappeared from under them. Depending on how much force you put behind the umount (as in doas, sudo) it is not entirely certain you would be able to umount a file system that has open files. Then again, your mileage may vary.
