Mirrored text is fine but why upside down

It has been really a while now.. have posted something here :) but its better late than never..
This post is about one of the head turning material that i got while i was going in for tea break on the other side of road (we do so because its small fun break even though we have very good pantry)





And i was wondering this is to seek attention of viewers and will act as publicity stunt or some more un-understandable logic behind it!! what you say??
