Which type is used depends on the ApiModuleManager responsible for the API module. There are two managers, one in ApiMain and one in ApiQuery. Both contain a list of API modules they instantiate. Both use $this as the first parameter in the constructors of the individual modules. There is no other regular way to instantiate the modules, so we know the type must either be ApiMain or ApiQuery. The lists don't intersect. I would have prefered the naming scheme $mainModule for ApiMain modules and $queryModule for ApiQuery modules but since this doesn't add much I left the shorter variable names untouched.
