Erm, maybe it's recommended, but that is really annoying for other isle passengers on long haul flights. Well I find it annoying if someone keeps standing by my seat and stretching. I was once in front isle of economy: someone thought it was fine to keep appearing and standing in front of me at regular intervals.
I’m one of these people. The reality is that I am too tall to fit comfortably in the seat and need to stretch my legs to get the blood flowing since it is hard to sit with your knees compressed for long periods of time.

That's a lot further than just stretching in the aisle..
I'm on the taller side and I apologize for any inconvenience, but I really do need to stretch. Those coast to coast flights will leave me paralyzed for days otherwise.
I sympathize with the post you're replying to. Mostly because butts are about face level in these situations and people don't seem to realize it would be more pleasant for others if they'd angle them away from faces.
