When having multiple firing rules in Tag Manager - "and" or "or"?

Question

Let us say I have some tag in Tag Manager.

This event has two firing rules:

1. "All pages"
2. "Domain equals domain.com"

Is this seen as an:

(1) AND (2)

or:

(1) OR (2)

This is quite important for how to add the rules.

Answer 1

This is answered in Googles own documentation:

A tag will fire whenever any one of its firing rules is met. For example, if a tag has two firing rules, one for "all pages" and another for "only page ABC", the tag will fire on all pages.

So... It is "OR".
