Yes, that's the one. If the video's to be believed, they could have turned round after entering IMC but chose to press on using the GPS anyway. Could be that the valley was already too narrow to do that comfortably.
I think we're both basically saying the same thing, which is that if you use things in a way for which they weren't intended, you can get bitten. I know there are aims to certify landings with synthetic vision, but I believe the vast majority of synthetic vision systems aren't yet designed for this.
In an emergency, of course...
