Were the two reviewers seasoned & well established or both with a single review? I'm not sure what you mean by "style & format" but keep in mind that a lot of reviews close the same way.

 "treat her right, fellas" or "She's a must see" or  "I'll be seeing her again soon"

Never mind the fact that men similar in personality may have similar things to say about a provider they both enjoyed, most positive reviews seem to sound the same, especially toward the end and especially if they are specifying that they'll be seeing her again. I wouldn't put too much stock in that particularly if the rest of the reviews have different styles and things to say. I would say it's a lot easier to spot a false review outside of tiny similarities.

Reviewers who Mimic other reviewers.  
You also said she was well reviewed.
That being said why punish her?

I would check the history of the reviewer. It might be interesting to see his scores and writing style.  It actually gives credence to his reviews.  

Unless you know for sure she wrote them then take them for what they're worth
