I'm assuming this is something he brought with him from Wichita? They still do it there.
Maybe they're standing to honor the Koch brothers at Wichita State.
Kidding and risking assignment to Siberia aside, traditions that are embraced and last tend to be organic. Like it or hate it, the "OU, Oh Yeah" cheer started pretty organically. Whether it was cribbed from Utah State or not, "Winning Team/Losing Team" started with a zealous student section.
I happen to think "We Stand for Defense" is stupid for basketball, but even if I didn't, it was installed inorganically by an AD telling a PA guy to say it. Much like the failed attempt to get fans to say "OHIO!" after a first down at the football games this year. You can't synthesize enthusiasm. People stand and cheer when their team does good things, not when they're told to.
