I take your point grizzled, the supposition that they had just had a selcal check previous to apparent loss of HF comms leads one to believe that HF comms was probably not a problem, even if they had gone onto standby, they would
probobly have got the selcal, presuming the controller tried contacting them on selcal. Selcal being more unreliable as vocal HF transmissions.
I would imagine whatever was going on up there, comms would be the last thing they would have considered. No 1 consideration is to fly the a/c.
