VK_NEXT behavior: By design?

void CXTPReportNavigator::MovePageDown(BOOL bSelectBlock, BOOL bIgnoreSelection)
{
    if  (!m_pReportControl)
        return;

    int nCurrentRowIndex = m_pReportControl->m_nFocusedRow != -1 ? m_pReportControl->m_nFocusedRow : 0;
    nCurrentRowIndex = min(
        m_pReportControl->m_pRows->GetCount() - 1, // Minus 1 - by design? I would expect the selection to go to the bottom!
        nCurrentRowIndex + m_pReportControl->GetReportAreaRows(nCurrentRowIndex, true));

    m_pReportControl->SetFocusedRow(
        m_pReportControl->m_pRows->GetAt(nCurrentRowIndex),
        bSelectBlock,
        bIgnoreSelection);
