The View Access plugin "Og Permission" doesn't seem to limit access at all. From my debugging it seems to be missing the function get_access_callback. Instead it uses the one that was inherited by the class views_plugin_access which always returns TRUE. I'm not 100% sure how the og_context_plugin_access_og_perm extends::access falls into this picture (probably need to talk to merlinofchaos about that, But it seems to be called by the display plugin after the menu access check. Probably for those views that don't use the menu like blocks and what not...
Anyway... This is the exact same issue inbut or 7.x-1.x-dev
