Yes, we want that story -- start a new thread with it! Hikers do that on a regular basis; fortunately it is infrequent.

Somehow, due to fatigue or low oxygen, or whatever, they miss the sign at the junction on the west side and down from Trail Crest. Somehow they don't realize on their way to the summit, that they have descended a little, so need to ascend at that spot. Instead of turning left and climbing the short distance to Trail Crest, they just head DOWN to the WEST, and into trouble.

Sure glad you were there to help the guy! The results could have been far worse.
