That's mostly incorrect. The plenoptic cameras don't record images in the traditional way; what they record is far more like the mosaic image insect eyes see.
Post processing converts the recorded data into a more typical view. One of the things the post-processing can do is recreate depth-of-field effects at an arbitrary plane of focus (including the sort of effect you get from a tilt lens, and even non-flat 'planes' of focus. Or, if you want, it can produce images with everything in focus. The downside of attempting to derive distance information (which is what you have to do to simulate depth-of-field), and all the other possible tricks, is that you will end up with significantly reduced resolution. As a ballpark figure, you're going to lose about one order of magnitude in pixel count - sometimes even more.
