What the article is saying is that if half of the other possible universes could still have lead to some form of life, even though formed with different properties than our own, then the odds are not 1 in one part in 1010123 (or whatever the number was supposed to be), but 1 in 2.
In other words, the Penrose calculation was about the particular set of physical properties of our universe, and not the chances of the existence of a universe with a set of properties which could still sustain life, even if those properties differed from our own. However, it is this later claim about life that some ID creationists are using Penrose to support.
A thought on life ~ it's so old, and so technologically advanced, that it really doesn't matter into which universe it is placed (or to which it travels of its own volition, or someone else's), it can, in some way, shape or form SURVIVE. This characteristic is what is misleading us concerning how it works.
I borrowed it from the local Multiversal Library.
