Doxygen seems lost when you changed the name of a parameter in class
templates.  Consider the following piece of code, where the
declaration of foo and its implementation differ on the name of
parameter: Key, or K:

/**
 ** \file misc/set.hh
 **/

/// Wrapper around std::set.
template < typename Key >
class set
{
  /// Union with another set \a s.
  void foo (const set& s) const;
}; // class set

// Union with another set \a s.
template < class K >
void
set<K>::foo (const set<K>& s) const
{
}

Doxygen reports:

Searching for member function documentation...
/tmp/misc/set/set.hh:17: Warning: no matching class member found for
  template < K >
  void set< K >::foo(const set< K > &s) const
Possible candidates:
  void set< Key >::foo(const set &s) const

If you use the same parameter name it works in both case.  Also, it
seems that the problem is not in recognizing that both are related to
the class set<K>, it seems to be related to the argument of `foo'.
Indeed, if `foo' takes void, or int, as argument, the problem is
solved, independently of the name of the template parameter.

Worse yet: Doxygen accepts happily the following incorrect C++ code,
where I have used `set' without template parameters inside the
implementation of `foo':

--------------------------------------------------
/**
 ** \file misc/set.hh
 **/

/// Wrapper around std::set.
template < typename Key >
class set
{
  /// Union with another set \a s.
  void foo (const set& s) const;
}; // class set

// Union with another set \a s.
template < class K >
void
set<K>::foo (const set& s) const
{
}
