F‏irst Qualifier IPL team at a disadvantage to get the purple and orange caps?

 

If there are any contenders for purple or orange cap in the IPL First Qualifier team, both are at a disadvantage to get each's coveted cap. 

Why? 

Could this be the answer?

The purple cap goes to the bowler with the most wickets. The orange cap goes to the batter with the most runs. The First Qualifier plays one game less than other qualifying teams. And, therefore, the bowlers and batters of the First Qualifiers won't be able to improve their scores. It is as if they are being punished for doing well.
