Pardon the omission of the requested details. I'm trying to be as vague as possible to avoid possible embarrassment to certain persons. Hopefully, this additional explanation will assist.
The person that counted the standing vote (the chair's personal secretary) announced to the chair that they still needed one vote, since the 2/3 required majority had not been reached. At that point, the chair contemporized that he wished to remain neutral, but was considering casting a voite. At that point, to me, it would seem that the vote had ended, with all parties (except the chair) having made their vote by standing or remaining seated. Before the vote was announced by the chair as having passed or failed to pass, someone that had been seated stood up, thus changing their vote.
At that point, the chair announce that the motion had passed, and entertained a motion to adjourn.
