or is it not that simple?

It's not, the cores are set up in parellel, one core can only process a single thread of data (one program typically). The reason why Dual Cores are better is one core is dedicated only to the game you're currently running, and the other one can do something else. Even if it's not fileshareing, or playing music or such, there are always background programs going, like the Operating System itself. Traditional, single core processor, everything is jammed into one stream and the game+operating system are programmed together, creating much more work per core and thus needing a faster single core to do the same amount of work as a dual core. So if the Duel core is slower, unless it's radically slower than a single core, it'll appear to be faster because the individual program isn't getting bogged down by the other junk that typically runs with I.E. The Windows OS itself, Firewalls, Virusscanners.
In a way it's an illusion or trick but it's far more effient. The only possible way dualism is a weakeness is when you're only running a single stream of data, one program. But as previously said, even Windows is a program, and unless you like staring at the desktop all day, you're always running at least two high processor consuming programs, thus able to use both cores.
The reason why dual cores are slower is because we have the same sized chips being made, but two cores jammed in instead of one. Heat becomes an issue in such confined spaces. And all the space possible is being used, usually this means have to cut down on the transistors used for one core to fit everything on to one chip. So we end upwith two slightly stripped down cores rather than one highly developed core. Two usually outdoes one in examples given. But it varies down to different design ideas and different types of processing. To view examples and gain more technical expertise, I would suggest you read
