AWS considers multiple facilities to be separate AZs in the same region. If you want multi region durability (besides us-east-1), you need cross region replication enabled (from the same FAQ you read).
"You specify a region when you create your Amazon S3 bucket. Within that region, your objects are redundantly stored on multiple devices across multiple facilities. Please refer to Regional Products and Services for details of Amazon S3 service availability by region"
Note, "within that region". Separate AZs, same geographic location.
"CRR is an Amazon S3 feature that automatically replicates data across AWS regions. With CRR, every object uploaded to an S3 bucket is automatically replicated to a destination bucket in a different AWS region that you choose. You can use CRR to provide lower-latency data access in different geographic regions. CRR can also help if you have a compliance requirement to store copies of data hundreds of miles apart."
This post http://shlomoswidler.com/2009/12/read-after-write-consistenc... has a quote from Jeff Barr at AWS indicating that us-east-1 is bicoastal, which is also why its eventually consistent, instead of immediately after a write (EDIT: it appears this constraint no longer applies to the US standard region).
