I disagree, Gowdy is just very careful and speaks like a prosecutor. That entire interview is interesting though, the way he talks about the Mueller investigation is basically a hint to Trump how to handle his defense that it was supposed to be a counterintelligence investigation and that's it. This fact makes it very odd that Comey wouldn't tell the us that Trump wasn't under investigation because it technically was a CI investigation targeting potential Russians and Trump trying to obstruct a CI investigation by firing Comey is obsurd.
