The significance of a guess that accurately got a character is small, and the longer you spend as part of the scene, the more truth you'll see in that.
During base there were many "leaks" that accurately guessed one or two characters. One even had Richter on it, and gained some traction on those grounds.
But it's just the broken clock being right twice a day; with enough guesses out there, some will line up to some extent. The Crash/Reimu/KOS-MOS leak has received a lot of mileage out of being one of those cases. And part of it is probably owing to confirmation bias, given the popular choices. And part of it is because there aren't a lot of other competing "leaks" right now. But it clearly just had a lucky ticket, and I hope, for the sake of letting it rest, that we see as much sooner than later.
