PVS-Studio warning V524 for MAME

class device_disasm_interface : public device_interface
{
  ...
public:
  UINT32 min_opcode_bytes() const
   { return disasm_min_opcode_bytes(); }
  UINT32 max_opcode_bytes() const
   { return disasm_max_opcode_bytes(); }
  ...
}

class device_debug
{
  device_disasm_interface *m_disasm;
  ...
  int min_opcode_bytes() const
    {
      return (m_disasm != NULL) ?
        m_disasm->max_opcode_bytes() : 1;
    }
  int max_opcode_bytes() const
    {
      return (m_disasm != NULL) ?
        m_disasm->max_opcode_bytes() : 1;
    }
}

This suspicious code was found in MAME project by PVS-Studio static code analyzer.
Warning message is:
V524 It is odd that the body of 'max_opcode_bytes' function is fully equivalent to the body of 'min_opcode_bytes' function (debugcpu.h, line 150).  debugcpu.h 151
