I would half expect a sauropod could just as easily use their long
necks to manhandle trees - smaller ones anyway. Twenty feet of muscled
neck packs a wallop. That same neck seems, to me, that it would've
made it more difficult for the sauropod to see what was happening. Could
it rear its neck back enough? Hmmm.

Sounds like it might be related to rear mount mating.
