Why isn't the GMT hand in the Explorer 2 behind the hour hand?

[WalterE]

I have been reading a lot about the new Explorer II 226570, thanks to this model's increase popularity and attention recently.

There is a design decision, however, that baffles me: Since maximising legibility is THE key design premise for this model, why assemble the GMT "freccione" on top of the regular hour hand?

Since the stem of the freccione is rather wide (compared to the regular GMT hand on the GMT-Master2) and not luminescent, it can easily obscure the regular hour hand, I suppose. Wouldn't it make more sense to assemble it at the bottom of the train, so that the shorter hour hand is always visible on top of the GMT hand? The tip of the orange freccione would always be visible underneath, since it is longer, right?

I realise caliber 3285 on the GMT-Master has the same arrangement of the watch hands, however this is less of an issue on that model due to the different design of the GMT hand.

There must be a reason that escapes me... I turn to you, oh wise WIS, for enlightenment!

Thanks in advance!
