Welcome to the Q&A Forum

Hi there, Really interesting question that I just noticed here. I've never done this before, but my best guess comes from the Google Guidelines on moving the site: https://support.google.com/webmasters/answer/83105?hl=en If Google recommends keeping the redirect in place for at least a month or so, the implication is that you can remove a redirect from site A to site B after a few months without significant ranking drops to site B. That also implies that removing a redirect from site A to site B will not return site A to its former rankings, because the link equity will continue to count for site B. That said, maybe it's different if Google sees the same content that people originally linked to. I wouldn't think so, though - 301 generally means permanent, no take-backs. You'll have to make the decision on whether it's worth it to remove the redirect based on how much it helped site B. Without knowing the details (was site A properly redirected to the same or similar content on site B? which site is more valuable?) it's hard to give you advice, but hopefully this gives you enough to reason it out!
