Noy,

My best shot at it after just pulling it up on JEPPS - is note 3 - depicting the VNAV DH - and stating the restriction. If you look at that VNAV glideslope it's 3.76 vs 3.77 on the ILS - they most likely would not have been able to depict that VNAV portion on the ILS page without it getting very confusing - again just a guess but since there was a VNAV portion to the LOC - with its own mins that differed from the LOC or the ILS - and they wanted to show that glideslope they went with the two approach plates vs 1.
