Yes but the number of singular plies in the same line is almost never 10 or 20 in that position and even if it is 20 in few lines it cannot ignore the rest of the lines.

I mean that if there are 2 lines when one has a score of 0.5 pawns for black and another has a score of 0.8 pawns for black the line with 0.8 score is not going to be extended so the position is going to get a score of at most 0.8 pawns for black.
