It is different, but the layout seems to be analogous.

In your case the files of interest are:
/sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:2f/LNXVIDEO:00/path
/sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/LNXVIDEO:01/path

In both cases LNXVIDEO:00 and LNXVIDEO:01 seem to be the Radeon and the Intel
graphics, respectively.

If that's the case, the attached dmesg output means that the power_removed flag
in the patch is set for the Intel graphics, but the hotplug event is generated
for the Radeon.  I'm not sure why at the moment.
