I tried this and it did go through a long process, restarted a few times, but the firmware version is still at 5.4.4.2. I thought the factory restore would reset the firmware back to whatever the factory original firmware was

You didn't reference the thread you are talking about, so no help there.
Minor elaboration to what j.p.s. already explained, the presence of this file effects a wipe of the user partition and settings, the visible USB storage in the /mnt/usr/ directory tree. This could be useful if there was problems or corruption in that directory tree and might be expected to fix some "your Kindle needs repair" messages.
None of which is what you assumed it would do. It won't restore, reset, wipe or otherwise molest the main or diag partitions.
