I don't believe changed names get taken out of circulation so I'm not sure what it would matter if Character A (or the account itself) is prevented from doing a 2nd name change service in 24h. It should have no impact on creating another character on your server with the name you want.
The only reason I can think of where it would matter is if you already have the max number of characters per server so you wanted to do two paid name changes to achieve your goal. In which case, like what Terrini said, you'd only be able to change one name per day.
