Is this notation correct?

Question

I have seen the following notation which goes against what I have learnt. On the picture, the red line is where I thought it should be as the decision must be made and the path goes from the diamond shape.

Answer 1

The decision "takes place" in the decision node, so the path must come from there, it is not correct to "make a decision" outside a decision node (at least not in any UML Diagram I know of, purely academic background). What type of diagram does that notation appear in?
