WEEB
If you are playing Call of Duty Black Ops online with the split screen option on Xbox 360, you have the ability to log in 2 different user accounts at the same time. If you log in 2 different user accounts at the same time, both players statistics and progress will be tracked while playing split screen. It will also show 2 different player online ID's while playing like this. If you choose to not log the second player into their own online ID, then yes, you both will have the same online ID shown while playing.
On Split-Screen Multiplayer you can use 2 different online accounts but only on Xbox 360. On PS3 the second player must play as a guest meaning all unlocks and ranking is reset after signing out.
