It also purges local backups if disk space starts to get too low. In fact, macOS High Sierra manages this disk usage seamlessly without user intervention. The reasoning behind this is that in the event the remote backup disk is not available or present, then you can recover files in spite of a missing remote backup disk and recover from the local disk.

You should always have at least 20GB of free storage space available at all times for the normal operation of macOS.

Plus you may have trouble mounting the APFS volume while booted to external media or with the Mac in Target Disk Mode unless you can manually mount the volume in read-only mode using the command line. Plus if you reboot a Mac with an APFS boot volume and that APFS volume does not have sufficient free storage space, then that Mac will not boot.
