I think that they get 2 points for reaching the doubles QFs, the same as for a singles QF.
It looks to me that the bottom note is just making clear ( but not very ! ) that for the L16 in doubles ( essentially R1 ) you just get the L32 singles R1 points ( 0 for a 10K ), but are thereafter awarded the same.
I believe the no points until reaching the SFs just applies to nen's futures events.
