This is a classic case of not reading one keyword: "via." The callout specifies Ø0.2 mm diameter typical via.

The solder paste example (on the next page) shows these vias in between solder paste deposits, presumably to help avoid solder being wicked into the via thereby not requiring plugged vias.
