No. As it shouldn't. A nickname change warrants a new TID. Houston Oilers, Tennessee Oilers, and Tennessee Titans all have different TIDs, and TIDs should be assigned to cards based on how they are labeled on the card.
In theory, DaveK_ND is correct that there should be two separate TIDs. However, this was a change behind the scenes by Admin himself. He has his reasons, and if you'd like him to share them with you, I recommend that you message him directly. Seeing as the change affected nearly 80,000 cards, I imagine that he had a pretty good reason for the way things are - or he didn't realize what happened and may need to be informed so that it can be addressed.
I'll never quit collecting entirely, but I am downsizing. Check out my COMC store and help me thin out what I don't want so I can buy cards that I do want. See something you like? Send me a message on here, and we can knock the price down quite a bit. I'll even take a bit of a loss if it means getting you a card you really want.
