AppImages are ELF binaries. So the answer to your question "how does my debian powered device know what to do", is that it knows how to run ELF format binaries. I'd assume there are technical descriptions available on how that works exactly, my seat of the pants feeling it's not much more than loading the binary into RAM and jumping to the binary's start address. As to how AppImages work, they seem to mount the AppImage file itself while running, presumably to gain access to more ELF binaries or other executables within. I don't really know, just an observation from the few occasions I've actually run an AppImage.
