I have just got tickets for the 2012 doubles. And I read through the rules and came across this (it may seem dumb but what the hey

)
Each player’s 875 point Force must contain 1
HQ
choice and 1 Troop choice from their respective Codex.
The remaining slots from the Force Organisation Chart
can then be used by either Force.
Does this mean that there is still a single chart for both players or one each?
