yes. this total set (from line 41) changes the behaviour from:

"Save and delete link are only shown for non-automatic groups. At automatic groups there is a message stating you can't change them" 

to

"You can save all groups but you can't delete automatic groups."

Meaning that the message which was displayed before is invalid, as you actually can edit (and save) automatic groups, too.

(But as you can see in the backend, for automatic groups it will only change the new added alias_level value)
