What is the point of Team Snake?

It's not crystal clear whether 'the sacrifice' alludes to the body used for the clone technique or the bijuu extractor technique mentioned in chapter 255, however based on what Itachi says after it and what Sasori says on the next page, it seems Kisame's statement should be interpreted to mean the sacrificed bodies were given 30% of the original's chakra.

To rectify with 255, it would make sense if Pein was saying 'even though you have a lot of chakra and this clone technique is good for you I will still need 30% of your chakra [for the clone technique]'. Instead of "I still need 30% of your chakra [for the the bijuu extractor]".

Or heck, it could even be both.
