Sometimes I accidently click on the conditional terminal of a loop and accidently change its stop condition. Then I may need to look at the code to figure out which condition it is supposed to stop on. If that conditional terminal had a label, that label could be set by the programmer to say which state is desired and quickly ensure the proper state is set. This would also help someone else who came along and looked at the code.
I currently set the label for Boolean constants for this same reason.
