It appears that Gary Illyes from Google said that if you have a link on a page and that link points to page A, but then you change that same link to point to page B - the value and relevance of that link changes as well. Marie Haynes quoted Gary as saying "the weight" of that link "will very likely change."
Again, this is Gary talking on stage, on the hot seat, answering tons of questions and then someone (who is smart and knows this stuff, but nevertheless) interpreting what Gary is saying in real-time and then me interpreting a tweet about what he said.
Here are those tweets:
A: (cont) if you change links it can change the relevancy. Google reconsiders how they use that link in ranking algorithms "and the weight will very likely change."@methode @jenstar #Pubcon
