Silly question about 'zoom'

Ok ok... I know from researching that comparing a P&S zoom (i.e. 4x) to a DSLR range is pointless. My question, and forgive me if this is stupid, is if a camera says xx-1200mm equivalent (such as the Canon SX50) does that mean you would need a 600mm lens on a DSLR to get 1/2 of the reach of the superzoom? Or is it not that easy either? Lol.
