Does resetting the rating on an app also reset the top "Most Helpful" rated reviews?

I have an app that hasn't had the ratings on it reset in almost a year. During that time it has accumulated a large amount of healthy 5 star ratings/reviews. However, the top review that shows on the app store product listing is a 1-star lengthy review. This 1-star review was at one time a 5-star and managed to accumulate enough "Helpful" votes to land it's way to the top of the reviews for the app. In a stroke of what I see as bad luck, the owner of this top review changed their rating to 1-star. So now when you visit the app page, you see this 1-star review. I am now trying to figure out a way to remove it. Reporting it does not do anything.

So my question, if I reset the rating when I submit a new update, will it also reset the top "Most Helpful" reviews?

I'm not sure about the rating of "Most helpful" reviews, but according to https://developer.apple.com/app-store/ratings-and-reviews/ it does not not reset your apps' written reviews.

In addition, keep in mind that resetting your summary rating does not reset your app’s written reviews. Past reviews will continue to display on your product page.
