Hi,

a bit experimental approach is using an integer point attribute (which initialized with 0 for one point) to grow over the whole geometry. Each time the selections growths the attribute increases by one. This will have the effect, that the neighbours of point 0 will have value 1 and their neighbours value 2 and so on. Using this attribute modulo 2 should give you the desired result. But this approach is a bit time consuming.
