We now know that Big Boss indeed was not in a coma during the initiation of the LET project, although it remains to be seen how they carried out the project without his consent. Anyway, the most recent addition to the timeline states that the LET project was "abandoned" in 1976, during Big Boss's nine year coma. So, I believe what happened was that since Cipher truly believed Big Boss was dead at that point they created Solidus, the perfect clone (we already know Solidus was created after Solid and Liquid, we just haven't known how long). Now however Liquid learned about the project, he probably didn't receive the full truth (that's how Kojima will make up for the translation error, while keeping the deeply entrenched belief that Big Boss was in a coma).
