They seem to be willing to test a second SNP when they guess right and get a downstream positive result on their first try, but I think it might be good strategy to wait until a SNP even further downstream is discovered, and then see if they will test for that one. Since SNPs can occur at more than one place in the tree, it's a good policy to at least eventually end up with results for the most downstream SNP known for a particular branch as well as one immediately above it on the tree.
