double or multiple

[Michael Sylvester]

 In some texts,it is double approach-avoidance conflict,in others-it is
multiple approach-avoidance conflict.
It would seem that there would be a difference between the two,but yet
these terms are used with the same type of example :A+A- vs B+B-
I can understand referring to the above example as double and multiple
should involved at least three options A vs B vs C.
Are conflicts only between two events?
