That was apparently present in the 70mm mix (and therefore the 16mm). Since you were expecting it, maybe it was present in a home video release at some point in time, but not the theatrical 35mm audio.
The yell was in the 70mm, 16mm, and 8mm mixes, but wasn’t on the 35mm mix or any home video mix until the SE. It’s possible a broadcaster could have gotten a source with it before then, though.
