Section 3.6.1 says:

The anniversary type of "VEVENT" can span more than one date (i.e., "DTEND"
property value is set to a calendar date after the "DTSTART" property value).

It should say:

The anniversary type of "VEVENT" can span more than one date (i.e., "DTEND"
property value is set to a calendar date at least two days after the "DTSTART"
property value).

Notes:

"DTEND" comes, by definition (3.8.2.2), always after "DTSTART". The span (duration) is the difference between the two.
