Connecting the two wires into a single crimped terminal may actually be a code requirement for the PE wire. If the two wires are connected as a daisy-chain, then they must be crimped together into the same terminal. Otherwise, it would be possible to lift
the ring that goes to the PE side and all of the downstream daisy-chained items would be left without PE protection. By crimping both wires into a single terminal, even if you lift
the terminal off the device (receptacle, switch, whatever) the PE daisy-chain will remain intact.
Since it is allowed by ABYC (subject to pull-out test, etc.) and since not breaking a daisy-chain of PE protection is a requirement of nearly every electrical
code, I would recommend actually maintaining the dual-crimp connection. And, since it is PE, you don't have to worry quite so much about insulation.
