It definitely shouldn't use the gender of the admin. Other than that I cannot say without further investigation.

I'll add a couple of others details, which may be important: I experienced this issue in the Hebrew Wikipedia. MediaWiki:Blockipsuccesstext was deleted there, so it is supposed to be equal to the message as it appears in MessagesHe.php, but actually it isn't.
And in the Hebrew Wikisource User:MediaWiki default deleted this message in 2007 with the summary "No longer required".
So it wont be lost i opened Bug 29450.
