No, they are simultaneous. They need to be. It’s only fair because the slow poke in the left lane is creating the problem, and yes the law in this case is fair.
Besides, there are two opportunities for a ticket, but if there is only one cop, he can only write one ticket anyway. How is he going to pull over the right lane passer and the left lane poker at the same time?
I have been a member of a group pull over. The trooper was helping someone with a spare tire in the other direction on I-35 when our group passed by. We did not know each other, but were traveling in a group going about 85. He came up behind each of us, and politely asked us to follow him. We all pulled over and got tickets.
LOL. Did he turn his flashing lights on?
I wonder what would have happened if any of you didn’t pull over. Would he have chased that person and let the rest of you go?
It’s pretty obvious you’re not from the Bay Area. 
I’m getting chills imagining the mess that would happen if the same number of cars traveling on two lanes at 65 were forced to use only one lane. Around here, people try not to leave more than fifteen feet between cars - a “two-second” distance is impossible, and any length large enough to hold a car soon will be occupied by a car.
Whenever possible, I take 280 instead of 101.
