If both cabs are the same impedance, then yes bad logic because you are feeding 2X the amount of power to the speakers in the 2X10 then you are the speakers in the 4X10.
When mixing a 4X10 and a 2X10, the 2X10 needs to be twice the impedance of the 4X10 (ie: 4 ohm 4X10 + 8 ohm 2X10, 8 ohm 4X10 + 16 ohm 2X10, etc).
