First, remember, T. rex's posture was *horizontal*, not vertical.
[Like a bird, not like a human, or even a kangaroo].
Second, two or three of the potential prey animals were of a size that
put their backs almost excatly on a level with T. rex's arms. Thus
T. rex could grab these animals by the back (near the backbone) without
even changing posture!
Whether they really did use their arms this way to immobilize prey is,
at present, impossible to say. But I do not think it can be ruled out

He could do that with his mouth, just like modern cats do.
[I have seen film of a leopard carrying a full-grown impala
up into a tree].
The peace of God be with you.
