There are two sets of electors. One set is Democratic and the other is Republican so before they get to the point of voting they have all ready determined who is voting for whom to prevent the exact thing you ask about.
EDIT:
There have been 158 instances throughout history of "faithless electors". Of them almost half of them changed their vote because the candidate died prior to them being able to vote, 2 chose not to vote at all and the rest (a little over half) either by accident or choice voted for someone other than who they pledged to vote for. Now if I remember correctly to-date only 24 states have legislation punshing faithless electors that range from fines to misdemeanors. While faithless electors have once postponed the election of a vice-president, they have never changed the outcome of an election to-date.
Yes, you are right - that is what happens.
The twelfth amendments deals with the election of the president. If something should happen that the electoral college fails to decide, the congress must decide. There is a full set of rules as to what happens and in what order to determine who the next leader will be.
Until refers to the time before something happens. Therefore, since could be considered its opposite, as it refers to the time after something happens.
They generally transfer power temporarilly to the Vice President.

When something happens that is the exact opposite of what you expected to happen, this is called irony. An example would be getting candles to relieve your stress and them accidentally burning the house down.
