Exactly, that's something people are not taking into consideration. Let's remember the game will be launched with the 2018 F2 season. If they let you race a full F2 season they would have to consider the possibility of Russel never winning the championship, but making to F1 anyway. That would be weird.
You are basically right but being forced to have two fictional drivers through your 10 year career in F1 is even more unrealistic. They will probably move to Ferrari or Merc after some seasons and replace Hamilton, Vettel etc. and run for Driver Championship.
Let's admit when we heard of F2 coming to the game for most of us the obvious career implementation was to start in F2 and progress to F1 by achieving some goals. These goals shoud not be always win the title but for example, beat yor teammate, finish in podium in 4 races, get 5 poles etc. I still believe this option is still the best way to implement F2 in career.
On the other hand as you would remember CM offered us to do a questionnaire around 2 years ago apperantly during their development process. There were questions about career mode and story aspect to be implemented in it. I believe the answers made CM to go to story mode path. There is nothing wrong with it but it should definetely not be the only way to do career starting in F2.
So I really would like that CM should give us 3 options to start career;
1- Start in F2 with official drivers and do full F2 seasons until we hit team goals. Then we will proceed to the relevant F1 team associated with F2 partner. Norris and Russel will also be in F1 when we proceed.
2- Story Mode as CM has implemented as of now.
3- Start directly in F1, like in F1 2018
