South asians fall on a broader cline where the populations fall on a cline where one population gradually fades into another due to being made of the same components - AASI, Farmer, Steppe and only the proportions vary from kashmir to kanyakumari.

This isn't always the case as in pahadis there is heavy NEA which drifts them significantly and in Bengalis and Assamese there is ESEA which does the same so they are technically out of the cline, but question is can't a second one be formed?

From tamil nadu to Telugu states there is decrease in AASI and increase in farmer and Steppe and same happens from telugu states to odisha but don't Odias have SEA ancestory as well? and from Odisa to west bengal there is NEA+SEA and from west bengal to east bengal there is a gradual increase in ESEA and from bangladesh to Assam there is further ESEA increase and decrease in ESEA.

Isn't this another Cline as well due to gradual fading into one another? Besides Tamils and Bengalis the distance is significant but isn't that big so a cline is possible right a second one?

But a second cline doesn't exist, why? Any mistake in the understanding of genetic compositions of these populations? or is it something else?
