I couldn't figure out why both rooks attacking wouldn't win same way. I decided to play out variations with Stockfish analysis. It appears both rooks win expect R1c2 wins b7 pawn quickly making following position slightly better.
Then I wanted to see why Stockfish initially gives only one winning line. It seems like R7c2 Nd2 Rxd2 gets prunned from the alternative line. Stockfish seem to find the winning line only around depth 25-30 when I run it locally with clean cache.
