There's the question of what the cows are fed. AFAIK, grazing isn't how most cows feed these days, and the high methane output may have to do with the feed they're given instead of grass. There was a post here some time ago about feeding cows algae, and that also reducing methane output significantly.

That said, even if grazing does result in a net capture if carbon, that doesn't mean that the problems associated with eating beef like we do go away. There's not enough pasture to produce the amounts of meat factory farming puts out.
