Maybe the problem is the Golden Throne. If the Emperor is a perpetual, then the Golden Throne may be preventing him from regenerating his body. Also, a perpetual can't regenerate instantly, it take a few hours to a few days, depending on the injuries that the person suffers. So the case might be that the Emperor was connected to the Golden Throne before he could have regenerated his body.
