When you extract the old fluid from the master cylinder reservoir then add new fluid aren't you just adding air to the system unnecessarily? Given that you are adding new fluid on top of old in the lives anyway? Cheers

Not really, you only get air into the system if you pump the brakes or suck through when the reservoir is empty. Lines are still full and sealed when you empty the reservoir. It's much better to clear out the old fluid to avoid contaminating the new fluid. Also, the process would be much longer if you had to draw through all of the old fluid as well.
