Did Bandai add elbows to the 1/100 variable Arii kits?

I ran across this auction for a 1/100 Bandai variable super 1S and noticed the arms swivel at the elbows.

I figured maybe the modeler modded them because the few Bandai 1/100 variables I have (the '97 15th anniversary reissues) don't rotate at the elbows. But then I looked closer at the auction pictures and noticed the seller didn't do any seam work on the thighs or legs. So would a person who wouldn't bother to cover seams do extensive mods to elbow joints? Or did Bandai at some point do some joint work on the arms so that later reissues can bend at the elbows?

It never had elbow swivels so it's a custom job for sure.
