It is directly checking for s3 to s3[1] and indicates that it wants to copy...

I've read over it and I'm reasonably sure that it's going to issue CopyObject, but it would take me actually getting out paper and pen to really track it down.

The AWS CLI and Boto are a case study in overdoing class hierarchies. Not because there's any obvious AbstractSingletonProxyFactoryBean, but rather that there's no instance that stands out as "this is where they went wrong" and nevertheless the end result is a confusing mess of inheritance and objects.

Not to mention the insane over engineering of a python 2.7-compatible async task stealing io loop which is slow as hell, and pitifully delivers a maximum of ~150MB/s with 30% cpu core activity. That's why anyone needing to regularly download/upload files from S3 need an additional library (s5cmd, s3pd, etc)
