While I haven't taken them apart, I have done that with other power supplies and ballasts. Duals are usually based on a single powertrain with multiple secondary turns off the main transformer. While that means that the secondary circuitry is dedicated to each output, the primary circuit is common.
When you use it in dual mode, you're pushing the primary to its combined peak output. Unless they oversized the primary side to truly accomodate double the power, running in dual mode will generate less output per output.

OH. I get it. I guess I was thinking of the old magnetic style
