I believe it's unnecessary.  In the pQuickHlpData->Stop(rSh) call that 
immediately follows Move() ClearCntnt() is called which then clears 
pQuickHlpData->m_aHelpStrings i.e. same result at the eliminated Move() 
call.

void QuickHelpData::Stop( SwWrtShell& rSh )
{
     if( !m_bIsTip )
         rSh.DeleteExtTextInput( 0, sal_False );
     else if( nTipId )
         Help::HideTip( nTipId );
     ClearCntnt();   <-------------------
}

void QuickHelpData::ClearCntnt()
{
     nLen = nCurArrPos = 0;
     m_bIsDisplayed = m_bAppendSpace = false;
     nTipId = 0;
     m_aHelpStrings.clear();   <---------------
     m_bIsTip = true;
     m_bIsAutoText = true;
}

BTW, the following comment is in my original commit message as I did 
think about the point you raised. Hopefully it's right :-)

"The only impact aTmpQHD.Move() has on pQuickHlpData is clearing
m_aHelpStrings but this is done anyway in the pQuickHlpData->Stop()"

Cheers,
Brad
P.S. point noted about keeping braces even if the IF statement only has 
a single statement.
