This happens a lot with legacy characters. They either get written to have aspects of their predecessors or their predecessors will be shown as having aspects of their successors. An example of the former is how the DCAU basically gaev Tim Drake Jason Todd's backstory while for the latter we have the Flash show giving Barry some of Wally's villains.
It's really frustrating because people see this stuff and use it as "proof" that legacy characters aren't needed and are interchangeable when they aren't or at least they shouldn't be.
I half expect Jaime Reyes to be a tech genius with his own company if he ever gets his own show or movie.
