Focal Plane In Relation To AF Lighted Points

I had often wondered but never really had an answer....but I am sure one of you will know. I have a K-30 and when I have the AF set to 5 point. When I focus, in many instances I will show multiple lit AF points within the viewfinder. I am curious, if I have more than one point of focus, does that mean that the same items with the indicator are within the same focal plane and that is how there is focus in more than one item. I am sure that there is not multiple planes that will still focus sharply when taken. Just curious

One plane of focus (dictated by f stop) and multiple focus points with a margin of error.
