Could black simply play 3 at the beginning?
As far as i could read the exchange 1 for 2 is still possible after the ladder has come to its end.
: 1 is necessary as a probe.

is a probe. Black must play out the ladder differently if White descends. So Black makes White choose before playing out the ladder.
