Homeowner. I dont know from where you eminate, but in Australia & I believe Plumbing is pretty much the same around the world, you have described a twin bank of hot water services.
The hot & cold water should be configured so that equal water pressure comes from both HWServices so that you should have the same draw off from each HWS. Therefore to answer your question both temperatures should be the same.
Regards Bob
