Note what Dustin said. Also that if this feature is installed that PS will
exit with a 1, which if ruby interprets that correctly will cause the
command to get executed.
You probably are posting something after testing it a bit, but note that
your logic says install this feature if it is already installed and do not
install it if it is not installed.

Notice how I mentioned if ruby interprets the exit code correctly above. We
have an open issue to work around this (I can't seem to locate it at the
moment).
Note that this is a ruby bug - https://bugs.ruby-lang.org/issues/8083
