Called Byakuya getting cut since this whole Shinigami battle royale started, but I digress. Senbonzakura's weakness is a bit vague, but as the flashback image shows, it does seem to be something Kubo thought of before. I never thought anything of distance between Byakuya and the petals - I always assumed it was just for artistic flair. Ironically, this also sort of justifies the means by which Ichigo was able to take on Byakuya back in the Soul Society arc - he was unknowingly exploiting this weakness, up until Senkei was activated.
