This is, as far as I can tell from your explanation, different than what

OK, apologies for the misinformation.
In any event, the matter is not fundamental to fair queuing.
According to the code and Toke in FQ-Codel there are separate state
variables for each queue,
whereas in FQ-PIE there is a single instance of state (see line 72-75 in
sch_fq_pie.c
<https://github.com/hironoriokano/fq-pie/blob/master/sch_fq_pie.c>).
This is [should be] equivalent to a PIE queue
which uses FQ instead of FIFO as a child queue.
As I understand the FQ-Codel draft, it seems to be fundamental to
FQ-Codel that each queue has separate state variables.
So my question is: is it indeed fundamental ?
P.S. comment on line sch_fq_pie.c should probably be updated
