I thought that the multi-solution pods - they're usually have differently-colored, for I presume marketing reasons - have pockets with different dissolve rates, so that the solutions are dispensed in sequence. I've not tested that, though.
It would be probably very difficult to engineer a good dissolution rate that takes into account the different length and water temperature of the pre-wash cycle of the many many different dishwashers out there. So no, as the video in the sibling comment shows, it's just fancy marketing.
He has another video talking about pods specifically:
Alec actually looked at that in a previous video of the dishwasher series. There is no "different dissolve rate" or "dispensed in sequence".
