Being in the same conduit doesn't affect their dedication. They are dedicated if they have their own breaker back at the box.
However, there is another consideration. When you run cables in close proximity to one another for more than a few feet, such as when they are bundled together or in a conduit, then the electrical code(where I live)requires that their capacity be downgraded. So there shouldn't be too many things drawing power from it. How much depends on the size of the cable, the power draw of what is plugged into the outlet, and for what length the lines are together.
I would have preferred plastic conduit rather than metal. Howwever, it is possible that your electrician is using the metal conduit as a ground.
