I think that's what he tried to say, if you recycle paper the carbon gets somehow released. But, in theory, the recycled paper will still come out as paper, thus carbon will still be there.

If paper never gets recycled it will continue accumulating in the landfill at a fast pace, so more carbon gets trapped over time.
If paper gets recycled the amount of captured carbon will be that trapped in the paper currently circulating. Even if some paper gets eventually trashed, it will not be at the same rate.
Modern landfills are airtight, so buried paper is sequestered carbon. Less buried paper - less sequestration.
