I personally think that it means that the Google engineers do some calculations about the average number of links that change during some specified amount of time -- either in general, or for some subset of sites, or both -- and then they measure if your site is above or below that average rate of change for links.

I can't see from the quote if it is links pointing in, or links pointing out, or both.
