This may be a quest-specific scenario, but the game is capable of having NPC's know where you are while you are hiding.
I once was waiting for a quest-giving NPC to come out of their locked house by using the wait button for 1 hour. When the hour was up I was greeted by some thugs who quickly took me out (my thief / assassin wasn't prepared).
So, when I reloaded I took a short walk to stand on a very small island in the middle of a large river nearby to wait for the thugs, and pick them off at a distance.
The first 2 went down without me becoming detected. The sneak indicator showed a partially open eye, and the third one was entering the river. Instinctively I retreated back a few steps to gain some extra elevation, and just then the third thug retreated.
He started walking up the coast and over the bridge. I then walked a few steps forward to get a better look, and just like that he turned on a dime and headed back to the shore where he was first coming at me. I then took a few steps back, and the then turned on a dime and started heading across the bridge again.
What I surmise is that every time I went forward and back I was entering and leaving the water, but only ankle deep, not enough to loose the "hidden" status on my sneak indicator. I'm betting that the NPC's path-finding scripts decided that if I were in the water, his shortest route to me was the nearest access point to water (the shore he went to when I was standing in the water). However, the moment I was on dry land his path-finding decided to find the closest piece of land to my chunk of land, which was the shore on the opposite side of the river, across the bridge.
It was definitely a fourth-wall-breaking experience, I could control the NPC's behavior, cause him to make a 180 degree change in direction, merely by taking a step forward or backward into or out of water.
