If that were the case then the first sentence wouldn’t claim that there are physical limits.
I dug up the paper.
“Biomechanical and ecological limitations notwithstanding, we estimate that the absolute largest T. rex may have been 70% more massive than the currently largest known specimen (~15,000 vs. ~8800 kg).”

That is the paper says, if we ignore biomechanical limits, statistically there could be a T-Rex that’s 70% bigger than what we have already found.
That does make sense, though I read it as:
[the new, expanded] upper body size limits…
Is how I read it, but your interpretation works well too, so I don’t really know now.
