Good question. The reason that both of them were able to use the Chaos Emeralds at the same time because both used half of the Emeralds power, but still was able to go Super. Chaos did the same thing. He used only half of the Emeralds power to become perfect Chaos and Sonic still became SuperSonic by using the other half of its power. It's like both of them are splitting its power in half 50-50. If one person used the Emeralds, they would be complete and have full power over the Emeralds. 😎 😎
Hmm did Shadow ever have a chance to do Chaos Control with a Fake emerald. No.
Shadow used a lot of his power fighting the BioHazard, the prototype of the ultimate life. If Shadow hadn't battled the BioHazard he would have lived. And the Shadow from Sonic Heroes is a clone with 1/10 of Shadow's true power.
