I'm absolutely certain.
The east and west feeds of HBO/Showtime/Max, etc have identical programming with a three hour delay. That is why they are the west coast feed!
The only exception is a rare one. Whenever there is a live event such as boxing and both feeds are showing the same event simultaneously, the movie preceding the live event on the east coast channel, usually follows the event on the west coast channel. The east coast channel has an hour of filler and then shows a movie. After about two hours, the two channels sync up again with the west coast on a three hour delay of the east coast feed.
See ya
