Yeah.....you weren’t in danger. I’ve had pronghorn do the same sort of thing when decoying them, and have yet to be gored to death or have anywhere near a “dangerous” experience. The bowhunter along for the shot often gets flustered and blows the shot, and one went back to camp and told his buddies how he was “almost attacked”. Maybe you and this guy were related. The closest anyone I know has ever been to having a “dangerous” pronghorn around was an orphaned buck which was raised from a fawn, which would get a little sporty and head butt people during the rut.
We won’t even get into your otherworldly reaction time, having time to spin around and face a 55 mph charging beast the length of a truck away from goring you into pudding.
