Display realname on Admin:Create confirmation page

I use realname module and username is replaced almost everywhere I just found two places where isn't and was just wondering whether it was done on purpose or just slipped through unspotted ?

From og.module :

line 790  t('Are you sure you want to make %name a group administrator for the group %title?', array('%name' => $account->name, '%title' => $node->title)),
.
.
line 830  t('Are you sure you want to remove %name as a group administrator for the group %title?', array('%name' => $account->name, '%title' => $node->title)),

I see that on other confirmation page you are using theme('username'... which works great with realname module.

line 1095  t('Are you sure you want to remove !name from the group %title?', array('!name' => theme('username', $account), '%title' => $group_node->title)),

Cheers
