Satlin: An Effect on Transylvania?

I wonder, as I read more about this man, I wonder what sort of effect did he have on Transylvania?

After all it was a joint choice to return the borders of Transylvania to its post 1919 border, and pre 1940. It was not his alone. In a way it must have been a calculation on his part, as he must have known that Hungary and Romania would be come satellite states of Russia.
Maybe it was the resources, and he never foresaw one thing, too many resources in one country means More power to that country.
