'Portrait Dialogue'. How does granting user rights in 'Dialogue Admin' work?

​In 'Dialogue Admin' in 'User Properties' there can be granted 'Access rights'.
A user has selected rights and not these that were not selected but has also certain rights that are not defined on the list.

For instance: A user with 'Allow user to design questionnaires' and 'Allow user to log on to Visual Dialogue' can login to 'Visual Dialogue', create questionnaires but also can create selections, create message templates but will not be entitled to e.g execute dialogs because 'Allow user to execute dialogs' was not selected.
