Makes sense. In the spur of the moment without thinking about it a ton, I would have scored it the 6-3. It's just interesting to think about how others would score it and their interpretation.
It can also be scored if there was no chance to get the batter-runner out but the fielders do manage to get a different runner out.
I got into a "discussion" over this one with a parent. The player had hit a fly ball to CF that dropped in front of F8. F8 didn't have a chance to get the B-R, but got the force out at 2B on R1. This was correctly scored as a FC. Parent was insistent that DD should get credited with a hit because F8 didn't have a chance to make the out at 1B. Parent was not happy.
