What's up with Google's Spanner SLA?

It has, what looks to me, like an unusual number of outs that allow downtime to not really count as downtime that makes you eligible for a refund. I'm not really an expert on public SLAs, but I checked the SLAs for other databases that are marketed similarly e.g., Azure's Cosmos DB, and they don't have the same funny escape hatches in definitions.
Since the SLA only obligates Google to give a 50% refund even if the service is completely down, it seems weird that they still feel like they need so many ways to avoid having errors or downtime count, as defined by the official SLA.
