I believe the behaviors you mentioned are in response to the effort to downvote. It's possible that rancho is just some steem noob millionaire that likes haejin and didn't know that his upvotes would be a detriment to the rest of the community. I don't know, and we haven't really heard from either one of them in terms of dialog. I do know that I'm glad it's stopped. Haejin was posting about 8-9 times a day. So if rancho had just continued to upvote only him, it could have pulled about $3000 daily from the reward pool.
