There's a logic behind it, but I was anyway a bit surprised.

N.B. Of course I solved easily using MPC.
I am curious, how did you expect it to play? On my computer, it becomes quieter and quieter with each repeat (which is what I expected it to do, based on the text note)
On my computer, the entire fade is on the first time. The repeats are all
ppp
Let me revise my earlier remark: it definitely fades during the first 2 repeats, and reaches the quietest level during the 3rd repeat, and stays at that level for the final repeat. I am curious why my computer would play differently. (Using Microsoft GS Wavetable Synth)
When I play back through my MIDI keyboard (Yamaha P-250 piano) it seems to fade faster, as in your case.
The MIDI messages the clip generates suggest otherwise:

I stand corrected. Maybe my ears wanted the fade to stretch out, but now I hear that it falls off right away.
