They don't say anything about it, I think.
It's an IEEE/802.15.4 issue.
6tisch specifies TSCH mode, which includes the ASN.
(To be clear: Christian is trying to come up with something non-TSCH that can
be used for plain 802.15.4, but which does not use 802.15.9 to do per-pair
keying)

The EUI-64 goes into the key schedule.
Different EUI-64s get different keys, even if the counter is the same.
