If want to use SSDs for caching the last thing you want is to keep them at
100% capacity - it takes too long to kick things out of the cache, just when
you need to put something new in.

I think the idea is they are physically at 100% capacity, even if not logically so. That is, they've probably hit full at some point.

Well, that's my guess, since it makes the most sense.

FWIW they have separate read and write caches (both SSD).
