No, those didn't drive more powerful system through the PPU of the less powerful system. They used a separate communication channel to connect to the graphics output of the host device.
It's the difference between hooking a device up your video card's input port and running a whole external computer system via the USB mass storage API. The latter is way more of an amazing hack.

The external frames came from a hardware Gameboy CPU, but could have just as easily come from anything else - an Atari 2600, an XBox One, an iPhone, etc.
