How to completely remove Fuse for Mac OS X NTFS-3G
I don't think this is a problem.

The pkgutil command is just telling you that the fuse_wait package has been installed on your Mac. If this is the only result from that command then it means the other fuse packages have been uninstalled, and since the fuse_wait installer only replaces one file in the fuse install that file has likely been removed from your Mac.

Also if you are running the kextstat | grep fuse command from the linked answer and getting no results then it further confirms that fuse is no longer running as part of your Mac.
