Other people have answered more thoroughly, but it should be added that even your source never calls grass fed beef carbon neutral (on the very first paragraph it even says that it isn’t), just that it has a better CO2 footprint than grain fed beef (and that not by much, as has been pointed out)
No, nor is its best case carbon neutral. See my sibling comment about that. It’s also worth mentioning here that the typical grass-fed production is actually higher in methane emissions due to longer raising times
Taken together, an exclusively grass-fed beef cattle herd would raise the United States’ total methane emissions by approximately 8%.
Or if we look at Australia, which likes to tout its grass-fed production, it’s still majority feedlot
51% of domestically consumed beef comes from feedlots.

In Q1 2021, 19% of cattle on feed were on feed for less than 100 days
And trend-wise, grain-fed rather than grass-fed is increasing
Going forward, these trends indicate that the Australian grainfed sector will continue to make up a growing percentage of cattle slaughter and beef production
Please link any study on livestock being CO2-neutral. I’m very skeptical, but would love to read your source first.
I don’t have access to my schools library atm. But here’s one I found off google (which is admittedly a poor method to find studies)

Full disclaimer I should have clarified in my original comment. Grass fed livestock specifically is carbon neutral

Are the majority of livestock grass fed?
