"Set" implies that someone arbitrarily defined it to be 13. Rather, that's the lowest mass at which deuterium fusion is believed to be possible.

The whole paragraph is misleading, suggesting that brown dwarfs always form as part of a multi-object system:
While some rotate around their primary like an ordinary planet, many more brown dwarfs exist in the depths of interstellar space, as these small objects are often ejected from the stellar nursery by gravitational interactions with larger stars.
It would be better as
While some revolve around their primary like an ordinary planet, many more brown dwarfs exist in the depths of interstellar space. Some were ejected from a system by gravitational interactions with other stars while others formed on their own.

since not all of either are solitary.
