If I add multiple conditions to the same rule, how do they work together?

All conditions must be true at the same time for the rule to act (it works like AND, not OR). For example, with the conditions Spend Greater than 50 and Purchases Less than 1, the rule only pauses items that have already spent more than US$50 and haven't converted yet. If you want alternative behaviors (an OR), create two separate rules, one for each scenario. Conditions appear as labels on the rule card, so you can quickly check what was configured.
