Yes, for neatness and predictability!
Imagine, if you will, if you targeted a 16 slot server. It is more noticeable when it's separated, instead of just a long string of random characters. Having it separated also makes it a lot easier to scan for player names in the logs too.
I just think this is one of those things that shouldn't be changed, just to be changed. There was nothing wrong with the old format. Sure it's kind of weird when you target yourself, but how often does that actually happen?
