When a DLP policy is created as a Shadow/Web Policy, it applies to all traffic by default. You can set criteria to restrict this scope, such as the location where the policy applies, the cloud service it applies to, or the users who it is imposed on.
For example, you can create a policy that applies to all users who are working on your data in London and Bangalore using the Dropbox cloud service. The data should be blocked for all of them, except for Bob Miller.

You have created a DLP policy as a Shadow/Web Policy that does not apply to all traffic originating from users who work on your data in the cloud, but only according to the scope you set for this policy.
Users are not allowed to work on your data in the cloud with Dropbox if they are based in London or Bangalore. An exception is only made for Bob Miller.
