Adding a Bind Event node in different ways can create nodes with identical names (Bind Event to <Dispatcher>), but under the hood they are actually different nodes.
Easiest evidence is that they have different tooltips. But there's also some difference in blueprint functionality. For example, one of the node types can be placed in a blueprint function, whereas the other can't.
Though these nodes have the same names, they are different nodes (they have different tooltips).
Either the same type of node is created regardless of the process of creating them, or the nodes have some naming distinction.
There's no existing public thread on this issue, so head over to AnswerHub just mention UE-80114 in the post.
