It is just a fun tool that mainly focuses on showing the randomness of the GE, there's not much to learn from it, besides learning how "lucky" you got this time, it means nothing for the next time.
I think that type of information can be interesting if it's done for a couple of big games per season, like the B3 Final and World Cup Final. But when it's used it should be publically and in a consistent way, it shouldn't be provided on an ad-hoc basis.
