I understand the argument that the 4 2 3 1 fingering fits the phrasing, although it is perfectly possible to play 3 1 3 1 with the very same phrasing, it's just a skill one would use in other circumstances anyway, but perhaps it is more natural.
I also have a slight reservation about the argument that one changes position three times while playing the four notes in each, which suggests the hand stays still each time then teleports to a new position instantly. In reality, the hand is moving up the keyboard to some extent through each "position", also turning, etc., to accommodate the motion. However, what I found after some 3 1 3 1 3 1 practise is that I more easily lost track of that upward motion and missed keys.
