When the creation of a product, library, program, or project does not specify a shared team but does specify Yes for the Private Access option (for product and libraries) or Project Members Only or Program Members Only for the Private Access option (for programs and projects), the Default domain that is created inherits from the /Private domain in the organization context instead of from either the /Default/PDM domain or the /Default/Project domain. The resulting hierarchy for a private Product2 context is as follows:

In this scenario, the domain hierarchy for the System and Default domains in libraries, programs, and projects is the same as the hierarchy for products.
