Why do all variant models build in accelerator mode when generate preprocessor conditionals is selected?

I want to run my model reference variants in accelerator mode. When I compile the parent model, I only want the variants selected by the variant conditions to be built. However, when 'Generate preprocessor conditionals' is turned on, all the variant models are built. The documentation here

http://www.mathworks.com/help/simulink/slref/modelvariants.html#bsc4smh-1

states that this setting should only be relevant for code generation. I do want Simulink to generate all the variant code for code generation, but not for accelerator mode. Is this a bug or does accelerator mode somehow fall under code generation even though it is a different license?

I've tested this with the rtwdemo_preprocessor.mdl example for reference and see this behavior there as well.

Thanks, Chris

Update: Mathworks confirmed that this appears to be a bug. They noted one workaround is to set the active model reference to normal mode, which will prevent the other variants from building even if they are in accelerator mode.
