Perhaps, but it's not clear this would fall under any syndication rights. It's also not clear if he was honest about having part of the deal, from your link:

> During the New Yorker’s investigation into the veracity of the claims, reporter Connie Bruck was unable to find records of payments to Bannon. However, it’s possible his deal was capped and paid out between Seinfeld’s syndication in fall 1995 and Turner Broadcasting’s merger with Time Warner in late 1995. Following the deal, Turner’s Castle Rock came under the Warner Bros. umbrella and the company started sending out all of profit-participation statements. Prior records from the earlier months of syndication are not readily available.

And:

> On the other hand, when Bannon submitted an “income and expense declaration” during a contentious court battle with his ex-wife, any Seinfeld profit participations should’ve shown up. The New Yorker surmises either the profits weren’t substantial or Bannon failed to disclose them in a sworn statement.

I bet he made a few bucks in the 90s and and used the allure of the show to impress people since then. Seinfeld is still generating massive amounts of money so someone should know if they're sending any of it to Bannon.
