Herse's (and others) use of front changer for captain most likely predates the use of curved tubes.

As I understand it, this arangement works very well and there are far fewer chain alignment issues as a result. Also, if the captain is indeed the "boss", the captain also needs to be in control of shifting. With a hand actuated derailliuer, the front shifter must be by the captain.

But Herse also used this arangement on bikes with cable actuated front changers as well. So my guess is better chain line is the reason (and better shifting). If it worked better the other way, then it would have been done the "conventional way".
