In this Video Acharya clearly says if Yajnopavita not done or done after time limit, 'शास्त्रीय परम्परा के अनुसार उसे ब्राह्मण क्षत्रिय वैश्य नहीं कह सकते'
We cannot call him a Brahmana Kshatriya Vaishya.
Bloodline or no Bloodline, the point is not about bloodline importance here. Main question is "Can Bloodline Determine Varna"? No. Because even with bloodline he is not Brahmana without lineage of Samskaras in Paternal Ancestry.
He shared Raghavacharya ji's video talking रक्तशुद्बि but that was from a video where His Holiness is Generalizing रोटी बचाओ और खून बचाओ, and explaining to mass in simple language. Even taking Daan from some adharmi would mean inheriting his Gunas and Karmas, so is taking food or blood from unauthorized guy, impurity still isn't physical but abt imbalance in Gunas.
Still I haven't denied same bloodline in Varnas and also can be said to not do intermarriage. But pt is can blood determine Varna? No
