Germany or Austria have more african admixture than Spain

If we look at Y-DNA African admixutre, Germany or Austria have more than Spain :

"Sub-Saharan African Y-chromosomes are much less common in Europe, for the reasons discussed above. However, Haplogroups E(xE3b) and Haplogroup A spread to Europe due to migrations from Northeast Africa, rather than the slave trade. The haplotypes have been detected in Portugal (3%), Spain (0.42%), Germany (2%), Austria (0.78%), France (2.5% in a very small sample), Italy (0.45%), Sardinia (1.6%) and Greece (0.27%). By contrast, North Africans have about 5% paternal black admixture.
