You err.  Symlinks are distinct i-nodes which are not the same i-node
as the destination.  A symlink is basically a file containing a string
that is read and then used a path to another file.

If you create a "hard" link (ln without the '-s') then you end up a single 
i-node that has entries in multiple directories.

[old-Unix-guy story: Way back when, SunOS used to allow you (if root)
to create a hard link to a directory.  It's not something you did a
second time.]
