Empty the pot and transfer the 2 pints from the pitcher to the pot;
Fill the pitcher again;
Pour yak sweat from the pitcher into the 1 pint space left in the pot until it is full;
4 pints will be left in the pitcher.////

Correct although you empty the pot by pouring it back into the bucket. But you're close enough.
