While the expansion itself may, or may not, function with game-share (as already stated by others, Bungie itself does not support game-share); the season passes included with the Deluxe edition, would only be granted to the account that actually purchased the bundle. Season passes cannot be shared, as they are essentially an in-game purchase item. If both parties wish to have full access to the expansion, plus the four season passes for the year: -Each account will need to purchase the full bundle for themselves. OR -One account buys the Deluxe, and the other will need to purchase each season as it releases, by purchasing silver and going through Eververse. (Again, no guarantees regarding game-share, so the expansion itself may or may not share.)
