Can you "roll back" an entire channel(s) using spacewalk-clone-by-date

I apologize if this is easily answered, but I could not find what I was looking for.

If I was to create a Clone Channel and keep it up-to-date using spacewalk-clone-to-date, is it possible to "roll back" to a previous date once you have made the channel more current that your target date.

For example:  If my channel was cloned to 2013-03-01 and I then clone to 2013-05-01.   Aftewards I realize that I did NOT want my channel to be that current and instead want it to be 2013-04-01.

What would happen if I did the following:

# spacewalk-clone-by-date --username=your_username --password=your_password --server=satellite_server_url --channels=rhel-i386-server-5 my-clone-RHEL-5 --to_date=2013-05-01
# spacewalk-clone-by-date --username=your_username --password=your_password --server=satellite_server_url --channels=rhel-i386-server-5 my-clone-RHEL-5 --to_date=2013-04-01

Thanks much!  I'm looking forward to the Satellite presentation at Summit this year for sure!
