Retrograde planets at birth in the natal chart is different from the transiting/progressive planets. An example is: Natal Mercury is retrograde. That doesn't automatically mean Transiting/Progressive Mercury will be in retrograde motion at all times, but rather inevitably have their retrograde moments in a years cycle. If you have Uranus, Neptune and Pluto retrograde in your natal chart, then yes they are retrograde in your natal/birth chart, but the transiting/progressive planets will not always be retrograde. I hope this is correctly addressed and explains your question.
