Am I missing something? Even if you have a fully refundable full fare ticket, you cannot change your reservation to get onto a sold out flight, can you?
I do agree with your post though, why anybody would pay more than they have to for a ticket is beyond me unless the company is paying for it AND there is a better than 50% chance that the return flight will be changed. Having a fully refundable in that case might make it slightly easier so you don't have to fiddle around at the airport to pay the upcharge.
