snapshot in both streams when workspace has mult flow trgts?

I am considering setting up a workspace with multiple flow targets so that a single build can be done using the source from two different streams. This is the way a customer wants to do it. My question is, with this setup, which uses the ant toolkit to do the accept, fetch, etc., when the changes are accepted, thus loading the workspace and creating a snapshot, will a snapshot be created in each stream? For recreatability purposes, I think a snapshot in each stream is necessary else how would you be able to get the same exact build source again in the future, if needed.

Thanks for the quick reply. I didn't realize snapshots could be made of various objects. I think what is happening is the teamAccept is making a snapshot of the workspace which, if set to flow with multiple streams, will save the data from both streams. If that's true then that's exactly what I need assuming I can later load my workspace from that workspace snapshot thus being able to exactly recreate that build.
