This is using the Anthropic principle to argue the point for the many worlds hypothesis because it is being argued that life is so fragile that it could not have formed without certain constants being how they were. So that there must have been a bunch of other realities that failed in creating sentient life.
The constants would apply outside the universe because the constants are invariant other all of our observations (the fine structure constant is an observed number and its value is arbitrary and if it was greater or less than it we wouldn't exist). But they aren't part of our perception they are part of our measurements.

So that there must have been a bunch of other realities that failed in creating sentient life. I don't think the existence or non-existence of sentient life in alternate universe is in anyway necessary for the argument. If we assume possible universes is a set parameterized by a constant C and if we know only value X gives a universe with the properties we observe, we can deduce C = X. If a value Y yields a universe with sentients that can't be us, we still know that isn't our universe and so we know C!=Y.
