No, no both buttons do not give the same thing. RAT MAN ON on the HYD section of the the overhead panel will deploy the RAT and give you BLUE hydraulic pressure only. It will NOT connect the EMER GEN when pushed. If you had a G and B HYD system failure (not loss of fluid) you may use the MAN ON switch to make it just a G HYD failure.
RAT MAN ON on the EMER ELEC CONTROL PANEL will deploy the RAT, pressurising the BLUE hydraulic system AND connect the EMER GEN. It was a question in type rating.
The initial responder's answer was not terribly clear or correct either. The RAT auto extends if both AC 1 and 2 are unpowered and the speed is above 100 kts. It's not a requirement in order for you to push the button - the switches are always powered - push them and the RAT will deploy.
