Yes, in the same way as is caused by SFQ's periodic hash perturbation.

However, in Cake this is a rare condition brought on by exceptional load;
it typically takes hundreds of bulk flows to get an unresolvable
collision.  The use of AQM also means that the extent of reordering is
reduced due to shorter average queues.  Most sane protocols, including
TCP-SACK, should cope fine.
