Yes.  Subglyphs of tricky fonts are also shifted and scaled
horizontally with bytecode – v40 intentionally suppresses that.

What do you want to say?

Indeed.  It's the horizontal alignment to the grid that makes the
renderings `sharp' and black, thus sticking out if compared with
`normal', fuzzier, v40 hinted glyphs.
