Once in a similar management dynamic, at my manager's request I compiled a presentation of several key points for a one-hour discussion, that my manager immediately hijacked for the first 15 minutes to lecture about why in the world I had started the numbered list of issues with the numeral zero rather than the numeral one. (It was a gating issue that was background to the others!)

So yes, I buy the hypothesis that 1:1 management grouping promotes non-ideal management behavior.
