I think you're missing the concept:
1st station in the AM has 3 empty cars waiting at the platform (the last 3 cars -8 9 & 10) for commuters to jump on & grab their preferred seats. A few more stations fills up those cars, so the last car (now full) doesn't platform at anymore stations until reaching the downtown terminal.
Meanwhile, at (say) the 4th station along the trip with the 10th car now full, cars 7, 8 & 9 are platformed. Car 7 is empty for those lucky commuters, but savvy ones may prefer car 8 which isn't too full & still has some good seats.
We know that some stations will have more commuters waiting than others, so one station may fill all 3 cars that are platformed, or it may take a half-dozen station stops to fill 3 cars that are platformed.
The train trundles onwards to downtown, and at each station a set of 3 cars is platformed, and sometimes the front-most car of that set of three is empty for those lucky commuters. By the time the train reaches the last station before the downtown terminus, the first 3 cars are used for boarding passengers. The front-most car is probably kept empty until these last two stations, since they may have the highest volume of commuters heading downtown.
Meanwhile the commuters with the longest commute (ensconced in the cars at the back of the train) are undisturbed during their commute by people shuffling on & off their car at every stop.
