A bug in the documentation.  The documentation reads

  Floating diary entry--entry applies if date is the nth dayname of month.
  Parameters are MONTH, DAYNAME, N.  MONTH can be a list of months, the
  constant t, or an integer.  The constant t means all months.  If N is
  negative, count backward from the end of the month.

  An optional parameter DAY means the Nth DAYNAME on or after/before MONTH DAY

But it should really say

  Floating diary entry--entry applies if date is the nth dayname on or after
  the first of month.  Parameters are MONTH, DAYNAME, N.  MONTH can be a list
  of months, the constant t, or an integer.  The constant t means all months.
  If N is negative, count backward from the end of the month.

  An optional parameter DAY means the Nth DAYNAME on or after/before MONTH DAY
