The iPad knows it’s orientation in space in 3 dimensions. What it does not know is where you are located in respect to it - if you set it down perfectly flat, and walk around to the other side, it won’t rotate the screen. The reason it picks the correct screen orientation (usually) when you set it down flat is you set it down in the correct orientation to begin with.
ETA: I see you’ve understood what I was saying.
BTW, there are some neat games that use the accelerometer - try the “Labyrinth” game - I think it’s still free.
