From the Max Planck response to the find:
"While supermassive black holes are often accompanied by substantial disks, black holes of stellar mass lose the disk created during the progenitor star collapse on a time scale of the order of τdisk ∼ 100 s."
In my association this connects to the dumbell-explanation of a single star source for the 2 BH and how quickly this dumbell-forming and colliding would happen.
Here, the two very short-lived accretion disks might have very quickly amassed enough to stream the stuff off into the void...just before they die in each other's arms,
to form a new BH.
There's a bit of tragic cosmical romance or a little soft-porn in it, don't you think?
