The one time I ran into a scenario like this it was an upper level executive looking to flex and show that they are the alpha. My manager and manager’s manager stayed after the meeting to tell him that my project met the specs perfectly. Later on I found out that every person who had been in the department over a year had gone through that exact scenario. I kept on working and ultimately it was fine, but the department had a lot of churn with people mentioning this practice in their exit interviews, end result was him getting promoted even higher.
