No, but your confusion is valid.

Borges (and Seaside) break data down into two types, session data and
component data.  Session data is persisted across the session, and is
not backtracked, while component data is backtracked.

You certainly could make the shopping cart component data, but it would
be confusing to most people.  For example:

Search for 'tuna', you'll get four results:

Akami Maguro
Chutoro Maguro
Ohtoro Maguro
Tekkamaki

Lets say I want to order one of each, so I click on Akami Maguro, add
it to my cart, then hit back twice, and do the same for the rest.

After adding Tekkamaki to my cart, I find that my cart only has
Tekkamaki in it, which is not what I want.

Component data makes navigation intuitive for the user, while session
data allows them to get work done.
