It is OR.
Assimilate FALSE to the empty string, and TRUE to any other string:
ε CONCATENATE ε = ε
ε CONCATENATE something = something
something CONCATENATE ε = something
What about both sides at TRUE:
something CONCATENATE something = somethingsomething
But because any non empty string assimilates as TRUE:
something CONCATENATE something = something
