I don't know, that seems pretty bog-standard to me. You redirect to HTTPS when someone requests HTTP when you want your traffic to all be secure. At least, that's how it used to be, these days browsers be be more aggressive in trying to hand you to the HTTPS version of sites if port 80 doesn't respond, and in that case it might make more sense to turn down port 80 as long as all browsers do the right thing.
