I think they are two problems with that particular design (in general I 
think the design works quite well - thats why the other video looks 
stupid):
1. The flaps are to small to apply force at the edge (I think, they made 
the folding part of the milk carton to small, maybe they did so in order 
to reduce the height and therefore the storage space)
2. They don't trust the glue to be weak enough to tear open at the force 
and rely on an overly complicated design where you have to remove the 
glued strip part - this leads to a bad edge over which you can't pour the 
milk.
In practize it has never been a problem for me, that the glue is to 
strong.
