Stockfish started game 47.1 a pawn up with an advanced central passer on the 6th rank. The white king was exposed a little despite castling. Komodo managed to regain the pawn and to exchange a few pieces on the queen side.
Stockfish pushed pawns on the king side and the evals started to increase. The engines continued to exchange pieces and the game reached a QRB vs QRN position. Komodo had a queen side passer, and the white king seemed to be open to attacks, yet Stockfish's eval was over 3.
Stockfish opened the g file and got a pawn to h7. Komodo was careful not to open the h file as well and tried to hide its king behind the white pawn. The combination of an advanced passer supported by the queen and an attack on the black king with the queen and rook was too much for Komodo. The game was soon adjudicated.
The reverse game 47.2 started similarly. Komodo did not push pawns on the king side. Instead the engines continued to exchange pieces and by move 34 only BN vs BN remained. Komodo's central passer and Stockfish's queen side passer canceled each other out, the game was adjudicated after a long shuffle.

Stockfish's king found a square where it could not be attacked by the black queen. The evals constantly increased as the engines moved their pieces, though it was hard to see what Stockfish had in mind. Komodo appeared to be in zugzwang, it made pawn moves and then its king moved away from the pawns. Stockfish managed to get its rook to the back rank and from there to attack the pawn on a6.
The two a pawns were quickly captured, Stockfish now has a queen side passer and Komodo couldn't stop it without losing the queen.
