I think that it is a positional test.

I did not check if the sacrifice is right but I found that the difference
between the evaluation before the move and the evaluation after the move is
small.

I think that increasing the value of the pawn can help programs to find Nd5 but
can also help to find some wrong sacrifices.
I guess that your program is going to find Nd5 because I found from games that
it likes to sacrifice a piece for pawns.
