There is an easy way to find out. Uncheck the checkbox and see if you will have 19 in the stats after it will generate again.
Right, there are real locationless and the "locationless" virtuals that are really in this list (ex. GCF55A).
For example, for me the numbers in stats and in top lists match, but I know that I did not find any "weird" caches, only the above one, which is falling into a country I already cached in.
If you want conclusive answer, you will have to wait for somebody with more knowledge about the code how are the top lists calculated.
