The head writer seems surprised (though happy) that some people are coming up with theories like that:
"My colleagues and I had a debate after the episode: Is it fair to assume that Logan was genuinely surprised by what Kendall did? Earlier in the episode, one of the shareholders suggests that he should step down. Is it possible he sacrificed Kendall knowing that Kendall might retaliate?
Okay, wow. It’s fun to hear that people are coming up with their own interpretations like that. It feels unseemly, given the work we all do to create [the show], to then impose some binary decisions. I’ll just say, the show is the best version of the show. I’m happy for people to engage with it."

It's clear that Logan was impressed at the end, but I don't think that means that he set up the dominoes to fall as they did. He didn't even know that Greg had the proof needed to pull it off. I think he was impressed precisely because he didn't see it coming and it was so strong. By contrast, he wasn't impressed when Kendall came at him at the end of the last season, even though that was arguably a killer move.
