It's not quite that simple. But broadly, yes, that's why I said it would

be modulated by the product of the alising. Gain is in the range (0,1] so

it will be amplitude modulated.
The alising is present in the sidechain, right? So a filterted version of

the alising will be present in the output of the gain stage.
