The phrase split brain I'm only familiar with in the context of DNS
architecture e.g. split brain DNS.
It's conceivable that someone might contort the nomenclature and refer
to a switch that supports VLANs as being configurable in some sort of
split brain setup, but best I can tell that's far from any sort of
standard terminology for switches.
A google on "layer 2 split brain" talks of split brain as a rather
undesirable situation that can occur if you goof up a
high-availability pair of their firewalls:

I am, hwoever, curious what you come up with and what motivates the
question.
