In Forms when you open an Exclusive gateway object and configure the Outflow paths it says

"After this object, the process will proceed to one or more of the destinations listed below"

I was thinking this seems wrong, since it says "Exclusive". Double checking the documentation on the support site it says

"Exclusive gateways split a process path into one of several outflow paths"

This was how I thought it worked, I think the wording in the Exclusive Gateway was meant for the Inclusive Gateway.
