You have not explained why you think it's wrong; Unless I've missed
something obvious in the picture, I can provide several reasons of why
I think it's right.  Discussed more below.

Also completely intentional.  Why do you think it's wrong?

In short, the envelope is being treated as data rather than metadata,
that is, an essential part of the audio rather than a completely
seperate thing that just happens to be overlayed (and should be
treated entirely seperately).  I wrote it that way because that's the
way I use envelopes: A amplification/attentuation mechanism that's
finer-grained than a global amplify and an essential part of the
data.  It's as persistent as the samples.
