Buddy said in the presser yesterday that he would only bring someone he offered the job to up to meet Mr. Wilson, and this was as a token of courtesy and respect to the owner. If you believe this (and I do) it means Nix had complete control of the search and hiring process.
Following this line of thinking, with the history Buddy has with Marty, it makes sense that Buddy would only bypass Marty for sound reason(s). He would know Marty better than most - things you could only know by working with someone.
There's gotta be something else there - something that there's no way any outsider (including the media) would know.
