Do accumulated yellow cards effect the MLS playoff games, or do they reset once the playoffs start?

Alonso, Montero, Hurtado, & Friberg each are slated to be suspended after their next yellow. The MLS site posted rules are not clear on this issue(see below)

"CAUTIONS AND SUSPENSIONS: A player will be suspended for one game upon receiving his fifth yellow card – regardless of the nature of the infraction which resulted in his being awarded a yellow card. A second suspension of one game would result after the awarding of an additional three cards as would a third suspension after the awarding of card number eleven. With the "Good Behavior" incentive it is possible for a player to have a caution expunged. If a player goes three games without receiving a yellow card, after an initial warning, the player will have one yellow card expunged. A player may take advantage of the "Good Behavior" incentive only once throughout the season."
