Two puzzles with the same position and a different solution

Those positions are clearly different, look at the pawns (never mind the white bishop).

The difference is that in one the d5 pawn and the white LSB are gone. In the other, they exist. Very similar positions however,

That are two puzzles in the same game, #106879 is two moves later than the first one.

Good review am i right?
Solidifies your understanding, not just that a move wins; you understand and apply.
