The second parameter is the "context" (textdoamin) of the string.  WP Core is assumed, so Core doesn't need the second parameter.  Plugins on the other hand, need to load their own textdomain, and then include the textdomain as the second parameter.

It's a fairly common mistake in plugins to use __() for translation without the textdomain. Doesn't work that way....
