In my opinion he is correct about not using IoC container in domain model. That practice I follow myself as well. Basic idea is that services may contain infrastructure dependencies and therefore its wise to mock them. Domain entities don't have those, so its not important to mock them up (still coding to interfaces is good practice).

Factories for domain entities should not be in IoC container, but factories for services should. Basically you may reference entity factories in your services. It's not very tight coupling.

Good reading about IoC can be found at Billy McCafferty's blog post "Dependency Injection 101"
