It's not the tree which does that. It's the organisms consuming the tree during the decomposition process which do that. And that doesn't happen all at once. Indeed, if you grow another tree then you're likely to still be net-positive.
If you use the tree for other purposes -- construction, for example. Or burning for energy production -- then it becomes a useful part of the lifecycle.
Doesn't that just release the C02 again? Construction purposes might help, or any other way of sequestering.
Probably other factors are small, but hard to predict (particulates, volatile chemicals, other effects of growth). Might be positive or negative.

as in the article. You could make chunky log cabin type buildings to use more. I'd quite like a log mansion.

New forest can store a buffer in perpetuity, e.g., a new trillion trees can store 133 Gt. But current emissions are > 40 Gt/year, so this is < 4 years worth of emissions.
