The reason, as I understand it, is the Maillard process that is responsible for the development of the characteristic snus flavors is sensitive to the pH environment, adding the sodium/potassium carbonate during the cook would prevent/impair the formation of the beneficial flavors that form more easily at a lower pH.
and while we're at it, Essential oils if you use them are added last because they are heat sensitive and adding them at the beginning of the cook would cause a good amount of them to evaporate away during the cook.
Just about everything else can be added in as part of the casing solution. In the cook I'm doing right now I included 6 grams of orange blossom honey and 5 grams of raisins at the beginning of the cook.
The cooking process only "needs" 25-30% moisture level. All the descriptions from the snus companies usually refer to the cooking process as steam pasteurization with additional moisture and pH adjustment after. I "think" (?) the cooking process works better in a steam environment (as opposed to a soup environment). You probably get a better cook in a steam environment as the steam is constantly cycling through the tobacco which aids in flavor development. The problem for the home cooker is he usually isn't cooking in a sealed container so he will loose moisture due to evaporation during the cook, so for the home cook it's better to start with more moisture than what is done in a controlled manufacturing environment.
I don't pretend to know any of this, it's just my attempt at understanding the process and why the professionals do things the way they do.
I notice little details, take for example the Gotlands snus video :
right at the beginning the screen caption says" here you see the pasteurizing cycle at the ending stage"
pay attention to the consistency of the snus when he does his "quality check on the tobacco mass" @ the 09 second mark.
