The capability of bonding two channels is coming from the Falcon Ridge Thunderbolt controller, not the cable. You can achieve the same with Gen 1 cable as long as you use Thunderbolt2 controller on both ends.

Thunderbolt 2 cables consume significantly less power than Thunderbolt 1 cables. This is significant if you are trying to use a Bus Powered Thunderbolt device.
