I think it is a two-phase operation. Ideally, once you get strut compression, then the spoilers only go up once you ALSO get wheel spinup to 60 knots. Compression enables them, wheel spin then deploys them, as a slight planned delay to avoid a hard nose drop (or trouble lowering the nose at all - not sure of 737 flight dynamics with ground-spoiler deployment.) In other words, normally, both strut and spin conditions must be met.
However, if there is a wet/contaminated runway with hydroplaning, and no or slow wheel spinup (and when one really, really needs the spoilers right now for drag and maximum WoW) then the strut compression alone will deploy as well as enable the spoilers once the lack of wheel spin is noted by the system "brain."
The fact the FCOM very carefully uses two different terms (enable, and deploy) means the writer is not using them interchangably. Enable means "capable of deloying" - Deploy means, well - "actually deployed." Armed, enabled, deployed - three different stages of operation.
Strut compression is necessary, but not sufficient - unless/until the system logic figures out the wheels are skidding and not spinning.
