An observation: this game is not symmetric.

I think it is mirror symmetric, and I think the confusion stems from "left for white and right for black". I believe the author means "files earlier in the alphabet" for both, and the different handedness comes from players generally sitting on opposite sides of the board.

(Imagine pawns being wrapped around king's starting position)

In the starting position, remove the major pieces. Treat the pawn row as a cellophane film, and pull it tight around the king, "sticking" the e pawn where it is. The d and f pawns also get stuck where they are, the c pawn gets pulled down into d1, the b pawn further pulled to d0 (offboard), and the a pawn down and around into e0. Similarly for the right half of the pawns, and now the position of the pawn relative to the king is the same direction that that rank's pawn grants power to the king. I do think this is a good mnemonic; anybody good at a quick animation? :P
