The relevant terms (paraphrased) are: number that can have life, percent of those which do have life, percent of those which have intelligent life, percent of those that release signals into space.

So that would just move the same math down one more step. Twice the number of planets which have life (whether you adjust "can have life" or just the percent of the above which do), but that cancels out with half as many either being intelligent or releasing signals.

Intelligent and releasing within our immediate galactic vicinity.

I don't understand why the aliens would waste power beaming directed and powerful signals into space.

Do you think the BBC bothers broadcasting enough signal for the Martians to listen to their radio? I don't think that's a very profitable business model.
