Why can't I glue carpet "loose laid" to DRIcore?

I have asbestos tiles in my basement so I want to cover them with DRIcore and then put carpet on top of that. Because I do not want to puncture the asbestos tiles with anything I can't do the "anchor the perimeter to the concrete" technique that DRIcore suggests. So this also rules out tack strips, pad and stretching as the unattached DRIcore panels would buckle/lift. That's all fine. I actually just want a glue-down industrial/office type of carpet down there anyway. So what I was hoping to do is just put down the DRIcore and then glue the carpet directly to that. But the DRIcore instructions say not to glue carpet or pad to the DRIcore. Why? What harm would that cause?
