PROJECT Master Yi's Armor Inconsistency

I suppose it isn't an inconsistency, but it just doesn't make much sense to me

If you look at his shoulders in his normal (non-ultimate) form, they are in a sort of inverted T shape

But in his Highlander (ultimate) form,

you can see that his shoulders have a T shape, but is right-way up.

I understand that these are sort-of 'hard-light' armor shoulders, but I don't understand why they would be a different shape or orientation.

It doesn't bother me to the point of asking Riot that they 'fix it', but I just wanted to bring it up to see if anyone has any ideas as to how this could make any sense.
