My analysis was flawed (hmm... me was under control of Belgium beer :-)

The task in not on the runqueue (p->on_rq == 0) at the moment when
put_prev_task_fair() and set_curr_task_fair() get its turn in
sched_move_task()... so dequeue/enqueue_entity() are not triggered,
that's good.

so back to the square #0.
