Because slugs can be numerical strings.

get_term_link() has this messy behavior of accepting different types
of arguments basically just for backwards compatibility with plugins
and themes.  As you can see from the comments on
<http://core.trac.wordpress.org/ticket/9323> my patch to make it
accept only integers went in to trunk long enough only to cause
backwards-compatibility issues on WP.com.
