that might be true ..
but then generally, conventional brake fluid is hydroscopic I think is

it absorbs water.
It will even turn completely to water eventually, or real water-like.
I wouldn't expect water to separate and collect in the bottoms of the
calipers,
but it can't hurt to bleed and flush there too.
