Lan Fan wasn't as content to fall to the ground as Greed was, after all she didn't have the luxury of regeneration. Almost the instant after they were both toppling she was already scrabbling for the wall with both hands, her mind forgetting the whole nudity aspect as well as her legs wound around Greed's waist in an attempt to stop him as well if she caught hold of anything--like the edge of the next windowsill down--or rather, the one after that as the first only slightly broke their momentum.
