Welcome to the forum! 
 
With Ariel's examples, the fullers clearly exhibit twistcore. I doubt that there is any difference in basic construction between Tiflis zigzag, Turkish ribbon, stars, what-have-you: made from twisted bars and differences in appearance result from obvious forging details as well as how much material is removed from the surface of the twisted rod. A rose is still a rose... 
 
BTW, twistcore is a widespread technique known pretty much all over the place; no need to invoke any specific connection with India. 
 
I'm less convinced that the fullers of the blade in the first post show twistcore - to me it looks more like pattern-welding with some surface manipulation from the limited pics. We need close-ups for getting a better grasp on its construction! 
 
Regards, 
Kai
