Needs Answer

I want a point not occur if overlapped with another point, but appear if this point it is not visible

For now my condition is :If[E ∈ {A, B} , false, true]

is ok. (thanks Zbynek and abakus)

I want now this condition:

If[E ∈ {A, B} AND {A,B} VISIBLE=true , false, true]

Is that possible?
