I’m guessing Roberts Rules stuff.
As a quick and dirty thing, you can call a voice vote of ayes and nays. If it’s not particularly close, it’ll be obvious what the outcome is, the Chair will call the result, and everyone moves on. However, any member can call bullshit on the Chair, and then it goes to a more formal process.
So without watching the whole damn video, it’s probably that the voice vote went one way, the Chair said it was the other, got called on it, and the roll call vote went against him.
Yes, definitely making excuses.
