I've noticed similar things at my university [am research faculty; disclaimer: throwaway account since my usual one identifies me].
Something I've seen often is unfamiliar faces specifically at seminars presented by academics of Taiwanese origin. My department has a pretty static set of seminar attendees, so it is quite noticeable when three or four undergrad-aged people I don't know slip into the back of the room.
