Yeah, but he built the satellite in response to an act taken by the League as a single, cooperating body. His fear, in building Brother I, was not that any one hero might go rogue, but that metas, en-masse, in well-meaning collaboration, were still too dangerous to not be monitored and analyzed and contingency-planned. It doesn't make a whole lot of sense to prepare to take down, say, just Superman, when you know he could talk half the League into backing his play if *he* of all people suggested a small, temporary, nearly reasonable tyranny. Add to that... you're League, and you pop up to the Watchtower and Batman is standing there with a gun and Flash is vibrating insanely and immobilely in a rictus of pain... are you going to give Bruce time to explain that really, he's the good guy here? It's just not smart planning to take down one Leaguer and not expect to have to deal with others. Thus, only two conclusions are possible: one, Bruce anticipated that his one-on-one solutions were sufficiently effective to work in concert if he had to fight more than one Leaguer at once, or two, those were not even remotely the plans that Batman would have made.
Pretty much the whole story arc supports #2, but unfortunately, there's not much we can do about that, because the story says they're his plans, quite explicitly. So we're left with #1, which means Bruce forgot about the teamwork factor.
Which, actually, is supported as a habitual failing of his by Bruce Wayne: Murderer and War Games and the Crisis lead-up, so as far as that goes, I'd say it fits.
