The dual black holes can have different sizes and different capacities to produce different sized stars.
They are assumed to produce most of the the plasma dust and and Hydrogen gas to form the central baby star.
The the size of both black holes is the origin of the polarization of the oscillating Higgs field vacuum (spacetime structure) in the HH system.
The Higgs field vacuum is assumed to be responsible for the maximum size of the baby star, before instability into a pumpkin star.
Pumpkin stars of different sizes, are assumed to be the start of secondary sibling stars and the start of an open star cluster producing larger or smaller stars and even failed stars or dwarfs.
