Sorry, no idea what that is, all I know of fuser is what POSIX says about
it.
-k automates the 80% use case of fuser --- "kill the things using this
file^Wmount point". (the other 20% being "output diagnostics for some human to
look at later".)
Looking at what I can see in SVR3, it appears "fuser -k" was used in the RFS
scripts to kill processes using a remote file system when the server was going
down. But I can't imagine why fuser would do the output interleaving if it
wasn't intended for use as "kill `fuser /mnt`", so I wonder if -k wasn't in
the original versions.
The source even has a comment about the output being intended to be fed to kill:

In SVR4, fuser -k was also used in the umountall script, if the -k option was
passed to umountall.
