Okay i'm not sure about this riddle but would i be right in assuming the coincedence part of the riddle refers to the specific blitzers names like : Datto,Letty,Keepa,Jassu,Botta and Wakka all having two of the same letters in the middle of each of their names aswell as only being 5 letters long? Don't know what the rest of the riddle could mean though.
