The EnergyPlus geometry model represents walls as zero-thickness surfaces, and the linked document is providing guidance on how to get from a building description that includes wall thickness (e.g. architectural drawings) to one that does not include wall thickness(the E+ input). If done badly, this process could end up distributing thermal mass etc. improperly. In many cases, the discrepancy introduced is not worth worrying about, but it is possible to override volume and floor area in the zone object to get what you need when the E+ calculated values aren't good enough.
