Yes, it's so that if the rear one causes minor damage or is itself damaged, e.g. by a piece of plastic on the OHLE, there's the possibility the front one and front section of wire remains undamaged and so can be raised and get the train out of trouble, I believe. The other way round and there's more likely to be damage to the rear one (or section of wires) that would prevent that.
I thought it was aerodynamics, since having the pointier bit facing the wind will reduce air resistance
Although that makes sense too.
I understand AWC use rear so that if the driver spots damaged OLE ahead (e.g. damaged dropper), the pan can be dropped hopefully in enough time to avoid a further damage or worse a dewirement. There are stories of this successfully occurring.The Pendo instruction is just AWC operating preference. If there is a pan fault you still see the odd unit running front pan.
Of course the factors you have all mentioned are relevant too.
