That is the format for specifying a pivot year to datenum. Pivot years are only used when the year is decoded as two digits -- which happens in this case because 13 is recognized as not being a valid month number. You can see that the first field is being interpreted as a month number by default by using datestr(734840) which returns 03-Dec-2011

The documentation of the two argument format says "format string FieldSpecIn" implying a string must be used. The three-argument format says "format FieldSpecIn" which does not inherently restrict to strings.
The documentation could use improvement ;-(
