If anything, this is similar to the case of John Henry / Jeff Luria:
Henry entered Major League Baseball with his purchase of a small interest in the New York Yankees in 1991. Henry became the sole owner of the Florida Marlins in 1999, purchasing the Major League club for a reported $158,000,000, which he ironically bought from Huizenga. In January of 2002 Henry sold the Marlins in a multi-franchise deal to Jeffrey Loria then owner of the Montreal Expos (now the Washington Nationals). Simultaneously, Henry led a purchase of the Boston Red Sox with partners Tom Werner and the New York Times Company from the Yawkey Trust headed by John Harrington.
So, Henry sold the Marlins, and bought the Red Sox at the same time. Luria sold the Expos, and bought the Marlins at the same time.
That does not suggest that the Marlins play in Boston, or that the Expos (Nationals?) play in Miami.
