the printed design or breakage pattern facing the opening?
Most chocolate bars have some kind of design, pattern or divisions where it will break embedded into the chocolate.
Most chocolate bars are packaged so the opening is at the back and the front is covered by full 'sheet' of packaging.
I normally open it at the back and break it from behind so never see the pattern or design.
To see that you either have to open the whole thing or pull it out and turn it over.
It makes no sense.
Why not package it with the design towards the back where the split in the packaging is?
