Same as the reason for Company's frontends doing that, then (only more 
founded in that case). If somebody reports a real problem caused by 
this, we can copy the corresponding fix more thoroughly:

- Remove the after-string from the overlay (moving its value to some 
other property) in pre-command.
- Restore it right away in post-command. And then update after the 
computation is made.

But we probably don't need this additional complexity.

Are you okay with the proposed change, then?

And how do you feel about reducing icomplete-compute-delay to 100ms at most?
