A L3 switch should first act as a L2 switch, i.e. it will forward the L2 frame to the destination MAC. S2, will write a new frame likely with a destination of L3 SW, as you show a L3 link between R and L3 SW.
If H's DG was L3 SW, then the original destination MAC would be L3 SW's.
It's also possible in the original instance, S2 would send a redirect message back to H.
