Apparently on some, the + and - volume buttons are the wrong way around.

Not looking good.

Odd thing is, the vid in ure link shows the buttons as correct

Guess someone wants to join the bandwagon lol

In philately (stamp collecting) mistakes like this can make the stamps much more valubable.

It looks to me like a labelling error which a lot of people probably wouldn't even notice, they would just assume that the top button increases the volume while the one underneath decreases it, without even looking at the little + and - on them (which are actually very difficult to see on that photo anyway).

Still embarassing for Apple, though.
