  In this work, we study the decay of $\overline{D3}$-branes in the setup of
Kachru, Pearson, and Verlinde (KPV) at higher order in $\alpha'$ from the
perspective of a nonabelian $\overline{D3}$-brane stack. We extend the leading
order analysis of KPV by including higher order commutators as well as higher
derivative corrections. Recently, the KPV setup has been studied at higher
order in $\alpha'$ from the NS5-brane perspective. It was found that in order
to control $\alpha'$ corrections the quantity $g_sM^2$ determining the amount
of warping in the Klebanov-Strassler throat has to be much larger than
expected. This leads to serious issues when using the $\overline{D3}$-branes as
an uplift to dS. The benefit of the analysis in this work is that the
$\overline{D3}$-brane perspective is controlled when the distance between the
branes inside the brane stack is substringy which is a regime not controlled on
the NS5-brane side. As a main result, we find that the strong bound $g_sM^2\sim
\mathcal{O}(100)$ obtained on the NS5-brane also holds in the regime accessible
from the $\overline{D3}$-brane perspective. We also show that the novel way of
uplifting proposed in the recent work on $\alpha'$ corrections to the KPV setup
can only work for small warped throats.
