Then how do you explain this?

I am not sure what you mean.

Why would filtered reviews distribution match up to the unfiltered reviews?

Typically a "fake" review is either going to be someone who is raving about a business to try to boost the rating or someone who for some reason wants to bad mouth the business (e.g. a competitor) so it makes sense that 1 and 5 star ratings are the most filtered.

Read it again. The distribution of filtered reviews doesn't match between average and the one for Yelp itself. Clearly doctored.

The evidence provided does not support your conclusion. For starters, 19 reviews are not nearly enough to make any comparisons.
