A hardlink simply attaches a name to a file in UNIX like OSs. You can give
a file multiple names by creating multiple hardlinks. These commands are
normally in /bin because in the past the root and /usr file systems were
separated and those commands were needed before /usr was mounted.

It is strange that those two commands point to different programs on your
computer. It may be a simple mistake. Or maybe the maintainers of your
distro did it to maximize compatibility among the ancient and less ancient
parts of the distro.
