Docs for grid --default-affinity imply a single affinity rule, no docs for behavior of multiple --default-affinity options

The docs for grid --default-affinity imply a single affinity rule, and there's no mention of how multiple --default-affinity options behave, particularly in regards to kontena grid update: https://www.kontena.io/docs/using-kontena/platform.html#create-a-new-kontena-platform

default-affinity - Specify the default affinity rule for the entire Kontena Platform using the affinity filter syntax. The default affinity rule is applied to all Kontena Stacks on this Kontena Platform by default. The most common use case is to prevent Kontena Stack deployments to specific Kontena Nodes unless specified in Kontena Stacks.

The wording on "The default affinity rule is applied to all Kontena Stacks on this Kontena Platform by default" is also misleading, it's only applied to services that don't specify any affinity rules. The grid default affinities are not used for services that define affinity rules.
