I think that's the same design as the remainder of the G series (I know it from my ancient G1 & G5) which use different resistances between two rings of a 4 pole jack, rather than simple shorting of sections of a 2.5mm stereo jack (as the latest olympus models do, as well as Pentax, Hasselblad, & many Canon models).
The Panasonic version is much more work to interface to other equipment.
Most of us do not need to interface to other equipment with that connection... We just want to use the remote as an electronic "cable release" to avoid camera shake. I have one I don't use. I simply use a two second delay, set from the camera menu.
I have used the WiFi app on my iPhone, but found that process almost silly when doing simple copy work (99% of my macro work is done on a copy stand).
