this is branch len, counting not only amount of empty cells, but we initialize it with that value. Later we add to this len 33 bytes for each existing cell (so 0xa0[roothash]).

How is the rename incorrect when it is counting the number of 1's in the afterMap bitmap ? 17 - number of 1's == number of 0s , right?

just read code block till the end and you can see that this variable is not just count of empty cells.
