He's saying that many (bad) ports are done by trying to stuff all the work of the 3 X360/Xenon cores onto the 1 core of the PS3/PPU core, because its cheap/easy to do so. That's basically why older PS3 ports tended to be subpar, relative to their 360 counterparts -- they didn't even try to use most of the Cell CPU, they just used the part that was basically identical to one of the Xenon cores.
Porting a game from the 360 to the PS3 is easy, if you're only using one of the Xenon's 3 cores to begin with. If you actually use the other 2 cores, you have to either write some new SPE code to do the work, or suffer a framerate hit since all the work has to be done on just one core now. Many, probably all, bad ports from the 360 to the PS3 basically chose the "framerate hit" approach, because its cheaper/less work.
