But if you kill a Hollow with a normal sword, it'll just die, right? But a Zanpakuto is different. Even if it critically damages a Hollow, it will revert to being a Soul and pass on to the Soul Society. The reversion is what's so weird. At first I thought it was some kind of sacred forgiving or cleansing power, but now that I think about it, that doesn't make sense (unless you just say that Kubo had a different intention when he wrote that, which would explain why we've never seen a Soul post-cleansing, as far as we know, with the exclusion of those that went to Hell). Besides the reversion, I'd say that it simply acts as a pass, or even a beam-me-up-Scotty teleportation to the Soul Society (or to the Dangai? Idk). After all, that's what Konso does. But if the Zanpakuto is Hollow itself, how can it reverse Hollowness?
