I remember reading about this. He was actually lost, in that he strayed from his trail and didn't immediately know how to return.
Rescuers were alerted because a family member had reported him missing after he didn't arrive home on time.
As the story goes, to the best of my recollection, the "lost" individual went for a hike and said they would be back before sundown. When they got lost, they obviously missed that deadline. They were biding their time in the forest until daybreak to try to find the trail to get back because it was too dark to look for it. So while he was "lost" it was mainly because the sun had gone down. He didn't feel like he was in any danger, and wasn't at any risk of immediately being harmed or killed; AFAIK they were reasonably familiar with that forest and they were more than capable of surviving in those conditions; so he had no motivation to seek help.
I get that he didn't feel like he needed help. But he told his family he'd be back before sundown so wouldn't the thought to call or even text your family to let them know you're ok cross your mind? That's the part that seems strange to me.
