Possible.
Yet only three samples from the Southern Arc paper's 700+ samples were L.
Two from Turkey - likely both L595.

"Armenia_ChL (Chalcolithic Armenia) All three males from this population belong to Y-chromosome haplogroup L1a-M27/P329.
The M27 mutation is common in South Asian haplogroup L Y-chromosomes1,2, but was absent in a survey of Y-chromosomes from Anatolia3. Haplogroup L occurs at a very low ~2% frequency in present-day Armenians4. Our results indicate that it was present in Chalcolithic Armenia, but the fact that all three Chalcolithic Armenians belonged to it should not be necessarily interpreted as evidence that it was common there, as our samples are from a single location (Areni-1 cave) and may represent a local founder population."
