Hi,
Based on my understanding, the author of the article was referring to a limitation of the popup action when defining a custom Window in it, where the Window could be used only once during the lifetime of the application. The default implementations of the popup action for Notifications and Confirmations do not have this problem, as they can be reused multiple times (but not at the same time.)
However, as long as you only need to show a message in the from of a Notification, I believe you could find the following blog post interesting, where an improved version of this behavior is described:
In the sample included in the aforementioned blog post, you should see that when clicking the Raise Default Notification button you are able to show several non-modal notifications as popups at the same time. Also, this popup includes the feature of defining if the popup should be modal or not through a XAML property.
I hope this helps,
