I think they're there to further reinforce the point that he's part of that group of sorcerers.

It's also not a bad idea to have both the Slumbering Dragoncrest Ring and Hush, since you'll sometimes want the effect but you can't afford losing the other rings/spells you're currently using, at which point you use the other one. It's quite possible that Griggs has both for that reason, assuming the same ring rules apply to NPCs.
