I never tried to make a "workaround of the spirit of the historical progression". If that's what it sounded like, I'm sorry. When I first started doing the contracts, I took the starters of the US, the Soviets, and Germany at the same time, as I try to take as many missions as I can as a general rule just from an efficiency standpoint. When I found one launch completed multiple contracts, I just went with it. Also, if this is a consequence of me doing a "workaround", then why has it never happened to me before? I've completed about half the American line at this point, as well as all of the German, French, Canadian, and British trees and have never experienced an issue like this in doing it.
