He is quite right! Europe/Samara and Europe/Volgograd in the present list are in the same time zone MSK+1, and Yekaterinburg is related to Asia.
Suggestion: to add Europe/Perm (or Europe/Ufa) with +5:00 (YEKT) and +6:00 (YEKST) to the list at http://www.livejournal.com/manage/settings/?cat=display.
