@VenturaVan; Autoptimize does not take logged in state into account (yet).
As far as I know WP Super Cache (and ohters, I guess) considers someone as being logged on if:
- the visitor is logged on (either as registered visitor in front-end or as author/ admin in the back-end)
- if it is a user who commented on the blog
For more info on this, I'm sure the WP Super Cache people can help. :-)
