PVS-Studio warning V502 for gridctrl_redux

void CGridCtrlDemoDlg::UpdateMenuUI()
{
  ...
  GetMenu()->CheckMenuItem(IDC_HORZ_LINES, MF_BYCOMMAND |
    (bHorzLines)? MF_CHECKED: MF_UNCHECKED);
  GetMenu()->CheckMenuItem(IDC_LISTMODE, MF_BYCOMMAND |
    (m_Grid.GetListMode())? MF_CHECKED: MF_UNCHECKED);
  GetMenu()->CheckMenuItem(IDC_VERT_LINES, MF_BYCOMMAND |
    (bVertLines)? MF_CHECKED: MF_UNCHECKED);
  GetMenu()->EnableMenuItem(IDC_SINGLESELMODE, MF_BYCOMMAND |
    (m_Grid.GetListMode())? MF_ENABLED: MF_DISABLED|MF_GRAYED);
  .....
  GetMenu()->CheckMenuItem(ID_HIDE2NDROWCOLUMN,
    MF_BYCOMMAND |
    (m_bRow2Col2Hidden)? MF_CHECKED: MF_UNCHECKED);
  ...
}

This code is incorrect as the priority of '?:' operator is lower than of '|'.
The program works correctly because of MF_BYCOMMAND == 0.
Nonetheless this code is potentially dangerous.

This suspicious code was found in gridctrl_redux project by PVS-Studio static code analyzer.
Warning message is:
V502 Perhaps the '?:' operator works in a different way than it was expected. The '?:' operator has a lower priority than the '|' operator.
