This is probably something that needs fixed after https://bugzilla.wikimedia.org/show_bug.cgi?id=20721 - which allowed admins without the abuse filter editor (called "edit filter manager" on en.wiki) userright to see private filters.
However, http://en.wikipedia.org/wiki/Special:AbuseFilter/history is still hiding (from admins without EFM) changes to private filters even though the admin has the abusefilter-viewprivate right in the sysop package.
