Quoting Otto [1] :

"From the interface side of things, it's not used for anything at all.

However, internally, it's possible to create terms that are aliases of 
other terms. These terms will then be in the same term group, showing 
that they're really the same term.

There is no real use for it at this point. It's there for potential 
future functionality and for plugins.

If you are a plugin programmer and know how WP works, then you can add 
an alias_of parameter to the call to wp_insert_term(). The alias_of 
specifies the slug of the term that the new term you're inserting will 
be an alias of (and so which will share a term_group). Same parameter 
works on wp_update_term() too."
