[cifs-protocol] SMB3 encryption over multiple requests

I just found out that windows2012 RC sends multiple compound requests
within just one encrypted SMB2_TRANSFORM message.
From reading [MS-SMB2] version 37.0 I had the impression that each
request would be encrypted on its own, similar to how signing works.
Can the other receiver side rely on the fact that all messages within a
SMB2_TRANSFORM message belong to the same session as the session (referenced
by the session id in the SMB2_TRANSFORM header) used for the encryption?
What will happen if a client send unrelated compound requests?
What about async responses with STATUS_PENDING, are they also encrypted?
How does it work, when the last request in a compound chain goes async?
Are Oplock/Lease Break Notifications encrypted?
Can there be more than one SMB2_TRANSFORM message within a transport
