My thoughts -

This current Serpentor is a third clone, but genetically enhanced by scientists loyal to Cobra Commander. There's a genetic tag within Serpentor that makes him loyal to Cobra Commander. He is genetically predisposed to do CC's bidding. Sort of like the clone troopers with Order 66. They have no choice but to follow Order 66. Same with this new Serpy, he has no choice but to follow CC's directives and there's no way he can get around it, except death.

He'd be a great battlefield commander and an impressive political "face" behind Cobra, stirring up whatever terrorist nations that can become Cobra allies. A great and frightening maniacal spokesperson for Cobra.
