From the post's author in the comments: "I think the levels of Germanic ancestry in Eastern Europe might be significantly underestimated, especially the Germanic admixture dating to the early Middle Ages.
It's likely that even Balts have non-trivial levels of Germanic autosomal ancestry, and they cluster east of Poles in intra-European PCA."
That would, of course, make perfect sense, since we know already that both during the Migration period, and afterwards during the Viking age and the founding of the Rurikid dynasty that there was significant Germanic intrusion into the area. While they seem to have mostly lost their languages eastward of a certain point, and in the 20th century, millions of Germans were literally expelled from areas in the east that they'd lived in for centuries, the point is that they did, in fact, live there for centuries, and while they maintained some cultural cohesion, there was no doubt plenty of admixture. Especially for those who became culturally invisible over time, like the East Germanic peoples and the late stage Vikings who founded the Rus.
