Imaginary or not the person who could not understand how to wire those dimmer masters and slaves and then took three days to find out how is not an electrician. He or she may have worked on electrical installations putting cables in place and maybe wiring them to accessories. ( lamps, switches sockets etc ) by following instructions. That can be done by people who can follow instructions but operate without any understanding of how electric circuits work. Many of these "house bashers" advertise themselves as "electricians" even though they do not have the knowledge to design an installation or to cope with anything out of the ordinary such as master and slave dimmers.
