Rattler,
this is wrong, according to the interview with the ATC, quoted and linked above
he "couldn't command them, just recomend".
This is not my understanding of PAR. But I might be wrong.
On the other hand the ATC complains about problems with communication,
he expected them to respond to his "suggestion" with the altitude
read back, but they didn't.
He speculates, they had problems with pronouncing the numbers in Russian,
so they chose to stay silent and continued this first approach on their own...
With the "known result", as he put it...
