A DESCRIPTION OF THE PROBLEM :
Right before "Details" part of format string explanation, the original text writes:

Another way to reference arguments by position is to use the '<' ('\u003c') flag, which causes the argument for the previous format specifier to be re-used. For example, the following two statements would produce identical strings:

   Calendar c = ...;
   String s1 = String.format("Duke's Birthday: %1$tm %1$te,%1$tY", c);

   String s2 = String.format("Duke's Birthday: %1$tm %<$te,%<$tY", c);

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The last line uses

"%<$..."

 for last argument reuse, which should be

"%<..."
