Carb heat off on short final?

Have had my ppl ticket for about 2 years now. I was taught when landing (lower rpms)to keep carb heat in until I taxi off the runway then clean up the plane for taxi to the ramp. I fly at a moderately used class d in Colorado. Watching a YouTube series today and this guy keeps taking carb heat out on short final. He mentioned keeping debris out and it's ready for a go-around. It makes sense to me (especially a middle of nowhere rundownish field) but is this taught differently at different spots in the country?

Edit - I'll add that the YouTuber is flying a c172 which is what I fly and why I was puzzled by the differences on short final.
