To help get a handle on the position, it is easier to understand the position with the e-pawns removed. In that position, the 4 vs 4 pawn constellation must generate a passed pawn as far on the far side of the board as possible. The rule of thumb to accomplish that is to start the action on the near side first, hence the move d5. The presence of the e-pawns does not significantly affect the play. I annotated this ending in detail here at CCC about a year ago. This position is relatively easy for a human, but hopeless for a computer.
