Yes, indeed.

Why does it applies to doubles? I would think that we needed accurate
equities for cube decisions, both doubles and takes.

Hmm, it's because a 2-ply cube decision is really comparing doubling now
with doubling next time, so it doesn't matter if some of the equities
are wrong? Still if some of the 0-ply equities at the 2-ply leaf nodes
are overestimated, we may overestimate the number of market losers,
hence, we double to early?
