*REARING* behavior. Self evident from reading.

There is very little time involved. Speaking from over twenty years in
martial arts, I can affirm to you things happen quickly. People think
there's all kinds of time in a confrontation but there isn't.
You can watch any nature show with filmed predator prey interactions and
see for yourself in regards to animals.
Besides, if you would go back an read what I wrote, I said "the sauropod
body would've come down right on it" (it being the predator). Nowhere is
it said stepped on, as in involving the use of feet. Imagine, if you
would, the belly area coming down on the predator. That is a *lot* of
weight, even for a short pushoff. No need here for a full rear. (which is
why I suggest the horse as a better behavioral model)
Plus, the front limbs do not have to be employed from a full rear in
order to be effective as a defense.
Now, a full rear is still permitted in defense. It could occur when
the predator(s) has been sighted (the sauropods did enjoy an advantage in
seeing distances and so forth. A full rear could've been a threat display
in response to a sensed attack.

I said behaviorally. Not skeletally. Two entirely different things.
Both the sauropd and horse skeleton permit rearing (the former as
explained on the jobaria web page).
