My guess over the years is because seating is too low for men. If seats were higher, men might more comfortable. Of course then, women wouldn’t like it because their legs would be dangling. Just my guess.

Having ridden on subway vehicles in NY, Washington DC, London, Munich, Frankfurt, Berlin, Hamburg, etc....I can say that when you have seats that go along the window....all guys do it. When you have normal seating...guys typically don’t do it.

I think you are correct. That was the first thought I had as I read. The height, the depth of the seats for the natural reason, and thoughtlessness as another reason.
