For more specific scenarios like this I've found that it's best to seek help on Twitter. Larry ****, author of the CBA FAQ, is probably the best resource out there. It wasn't this instance but another in the past where an incentive seemed team specific and he explained how incentives move with players.
IIRC the instance being discussed then was whether a team made the playoffs or not because someone was dealt from a contender to a lottery team. They became a free agent at years end because they gained an opt out clause since their team missed the postseason. The team that traded them made the playoffs still but that no longed mattered since that team didn't hold the contract any longer.
