I would be very surprised if their legal department thought the "basically" column was a good idea. They can say that it isn't legally binding, but that claim isn't ... err... legally binding. Everything written in a contract is equally binding, and the proximity and one-to-one mapping could make the summary column part of the contract. If either party is surprised by conflicting claims, it will be up to the judge to decide which parts of the contract are stronger.

The "basically" column is a really bad idea. The "full" column should stand on its own. If they think it is too complicated, it should be simplified.
