The idea for a starter is to help create a more perfect environment for your beer. There are no rules for what you can or can't do to a beer. The idea being we want to make the beer do what we want it to do.
Adding a starter to your already fermenting beer, I guess could oxidize the beer. I don't know how noticeable it would be. The bottom line is though, once your beer is started visibly fermenting, the fermentation has already begun long before and the yeast already fermenting would outnumber any yeast you would add (on a reasonable level).
