When indexing a tax book, what does it mean when you encounter DO in the name section?

Do is a variation of ditto.

The General Indexing Guidelines of the Project Instructions might be of help here:

DITTO MARKS

• If a record has a ditto mark or other sign of repetition, type the corresponding information from the previous record or field.
• Do not index the word "ditto" or the ditto mark itself. Other signs of repetition may include the abbreviation "Do" or a vertical or horizontal line.
• Sometimes you will have to depend on contextual information to determine whether a mark indicates repeated information from an earlier record or field, or whether it means something else, such as that no information was given for that record or field.

For the Tax Records though, if the ditto mark is the EXACT same name as the one before it, then you would not need to create another record. We are indexing unique names. But, if one of the names is different, then you would create a second record.

• Index each unique name. Some names may be duplicated. When names are exact duplicates, index only the first instance of the name listed. Skip the other exact duplicates and then index the next unique name. When the middle initials or the given names or surnames are spelled differently, please index these unique names.
