Sorry, I missed a point in your original question... that the provider was goes over and records (again) a complete ROS in the chart.
If the doctor re-records the exact same ROS items, then I guess you could probably get rid of the patient's version. But, if there is anything else on it pertinent to the E/M or demographics, then I'd keep it.
I'll go on to mention a point about duplication of effort and efficiency... (some of this may apply)
Either you're wasting the patient's time having them complete a form if the provider is going to just record or perform a complete ROS anyways.
Or, you are wasting the provider's time. You can be a little more efficient with the provider's time by having the patient complete it, and then having doctor review and initial the form and just notate the chart that it was reviewed (or anything pertinent to the chief complaint).
In today's day and age with all the extra work needing to be done for compliance, MACRA, MIPS, PQRS, efficiency is important. Wasted time = wasted revenue.
