bringing in a ground wire from the main panel is not bonding as your emt is being used to carry current circuits and the emt could potentially be seperated at a point creating the continuity to be broken.
Unless that green wire that you bring from the CDP in the emt with all your cicuit conductors is going directly to the grounding electrode without any joints, it is a bonding conductor.
Maybe I just don't understand what you want to know. If you have cicuits in emt and you decide to run a bond conductor in the pipe. Then you have the emt bonded by means of the emt and it is also bonded by the bonding conductor inside it. As long as you properly terminate the bonding conductor at all the boxes and equipment it means for a really good bond to ground. The wire inside is good practice for conditions just like you said about the emt coming apart.
I would say that it would be best to forget about the word ground unless you are at the service or transformers or a couple of other instances. Everything past the service is BONDING.
Maybe just give an example with yes or no type answer that you have.
