How is the scoring of Tie break different to that of a game of tennis?

If your playing a set tie-break (7 point), or match tie-break (10 point) they are the same in scoring. The person to start serving the tie-break only serves for one point. After the first point the other player gets to serve for the next two points, after those two points the player who started serving serves for two points and so on and so for. To win you must win by at least 2 points. When the score of the tie-break can be divided by 6 then you switch sides, ex. 5-1, 3-2, 6-6.... Here is an example of a tie-break. Player A (PA) and Player B (PB) are playing each other, PA was serving and won the last game to make the score 6-6 in the match. PB starts serving the tie-break, PB's first serve is a fault, the second serve is an ace. The tie-break score is 1-0 PA leads. It is PA's turn to serve, PA's first serve is good and PA wins the point, score 2-0 PA leads. PA is still serving, PA's first serve is a fault, PA's secon serve is another fault, score 2-2 PA leads. PB serves is now up to serve, PB's first serve is an ace, score 2-2 tied. PB is still serving, PB's first serve is another ace, score 2-3 PB leads. PA's serve, PA wins the point, score 3-3 tied. They switch sides. PA is still serving, PA loses this point, score 3-4 PB leads.....
