Right. But the difference here is you need to answer the question which is a task. Then based on what you actually want to do, there is an extra step in opening the dialog just to choose the other format etc.. maybe you just want to save in the application default. The point of the version I posted is that each button maps to a direct intention. The message is informative, and the user does what they want. It's not the application asking or warning or assuming anything. It's not the developer imposing anything. Based on what the application can do, the user is presented with the various options that map to intentions.
