Conditions Logic Order? OR, EOR, AND?

Hello,

I am getting baffled by the WooSidebars, but only because I am not sure how the conditions combine. Trial and error does not seem to be helping me, strangely.

Which logic is processed for the conditions?:

• condition1 OR condition2
• condition1 AND condition2
• condition1 XOR / EOR condition2

And is there an order to them, ordered like the tabs?

I ask because I want to apply a sidebar only to a combination of:

1. all posts in a category or its child categories
2. one page (that has a shortcode that lists the above posts)

Any help appreciated… something so apparently obvious seems to be escaping me….

Thank you!
