1 mini-bio per person

I think it was a couple of years ago that the number of allowed mini-bios per person was reduced to 1. This rule is also stated in the guide (https://help.imdb.com/article/contribution/names-biographical-data/biographical-data-guidelines/GMT9T242VQADZUQM#bio).

However, I came across this page (https://www.imdb.com/name/nm7029724/bio/) and wondered if there might be more cases like this. Is it possible for IMDb to check if there might be more name pages with more than 1 mini-bio so that these can be fixed as well? Or was this just a one-off case?
