PVS-Studio warning V501 for ACE

bool URL_Base::strip_scheme (ACE_CString& url_string)
{
  ...
  ACE_CString::size_type pos = url_string.find (':');
  if (pos > 0 &&
      url_string[pos+1] == '/' &&
      url_string[pos+1] == '/')
  {
    ...
    // skip '<protocol>://'
    url_string = url_string.substr (pos+3);
  }
  ...
}

Most likely this is what should be written here: url_string[pos+1] == '/' && url_string[pos+2] == '/'.

This suspicious code was found in ACE project by PVS-Studio static code analyzer.
Warning message is:
V501 There are identical sub-expressions 'url_string[pos + 1] == '/'' to the left and to the right of the '&&' operator. INet urlbase.cpp 205
