If you look at onModified event documentation - https://surveyjs.io/Documentation/Survey-Creator?id=surveycreator#onModified you will see that there is an options parameter and events could be filtered by type.

I modified your example: https://plnkr.co/edit/FGurjjgZ5zJImOpZ

There you can notice thai when you add a question to empty creator page there is three events with the different types:

modified 1 {type: 'PAGE_ADDED', newValue: t}
modified 2 {type: 'ADDED_FROM_TOOLBOX', question: t}
modified 3 {type: 'PROPERTY_CHANGED', name: 'pages', target: t, oldValue: Array(0), newValue: Array(1)}

First event says about added page. Second - about adding new question. Third is the common event fired on every property change. Property pages is changing when page added.
