Yes, because 10 was never an option. The NFL required the team that relocates to Los Angeles to play a game overseas for the next 3 years, so the maximum number of preseason/regular season home games is, and always has been 9 for these fans.
So either Kroenke says "No, I refuse to play a home game overseas" and therefore doesn't qualify for relocation, and therefore fans in LA get 0 home games. He said he agreed to play games overseas, as did the other teams, which allowed him to qualify for relocation and win over Spanos/Davis. Fans in LA get 9 games.
10 was never an option.
Beginning in 2019 you wont see the Rams playing any home games away from Inglewood for a very long time.
