Comment (by SergeyBiryukov):

 Originally introduced in [12609], expanded in [16272]. `network/admin.php`
 was added in [15481].

 Looking at [16272], I guess the checks are there just in case the one in
 `network/admin.php` gets removed at some point (it might be an oversight
 as well, but seems unlikely).
