How do bookmarks help when reviewing a large NC program?

Direct answer
Bookmarks let a programmer mark important lines and return to them without recording line numbers or repeatedly searching for code. They are useful for staged reviews, hand-edited sections, suspected trouble areas, and places that need a second person's attention.
Practical checkpoint
Use consistent bookmark names or review conventions so the marks communicate intent instead of becoming unexplained personal reminders.
