Using Different Coordinate Systems with Overlay and Append Tools

I've been working with ESRI software for 28 years but I guess somewhere along the line I missed a memo or two   Does the ESRI software no longer need the source and target feature classes in the same coordinate system for things like Append?  A (younger) coworker told me that ArcGIS Desktop does the projection on the fly in behind the scenes automatically.  If there are no reasons to have the source and target in the same projection we can eliminate the need for a staging copy when updating the Web Mercator copies we maintain for map services.

 

Does ArcGIS reproject on the fly in all of the Overlay tools too?

 

Thanks,
