It is proved that every element [c]∈R _wtt /M _wtt except the greatest and least elements is branching in R _wtt /M _wtt, i.e., the greatest lower bound of some two elements greater than [c], where R _wtt /M _wtt is the quotient of the r.e. wtt degrees _wtt modulo the cappable r.e. wtt degrees M _wtt.
