How can I "checker deselect" vertices of a uv sphere correctly? I'd like to select every second vertex of an UV sphere using "checker deselect"

I tried it like that:


select all vertices with "A"
Chose "checker deselect" from menu


But the result looks like that:



Only the area within the 3 meridians in the middle look like how I expected.
For the the rest of the sphere whole latitudes are selected, what I don't wanted !?

Some ideas ?
You have to deselect the pole vertices before doing Checker Deselect :
