I agree. Running steadily could have worked all the time, but then defending Moscow for too long without the flexibility to step back very often leads to a collapse of the front, and an early loss by Soviet player which they don't deserve.
On the other hand, Soviet probably can afford to lose at least Moscow, if not both, in terms of industry and manpower. Therefore, if both opponents can agree on a house rule victory condition and disregard the Bitter End victory points, Soviet players may have a better room to maneuver and fully utilize their skills.
You can maybe loose the industry, manpower et everything at moscow and keep fighting, the problem is the victory point for the scenario bitter end that is based and balanced on historical results.
(As it should be, but then moscow fall very easily unlike in real life.
Unlike real life also, the german army can concentrate troops to take moscow and leningrad because it do not need the caucasus oil to be able to keep fighting a war of movement).
