@RefereshScope in Spring config server

As per the documentation whenever the bean in RefereshScope and the actuator end-point refresh called the bean got refreshed.

Questions :

1. Bean refresh means spring load the bean again?
2. If Spring load the bean again and A bean is in a refresh-Scope and B bean contains reference of A, Will the system again load the Bean B.
3. If I marked all beans as @RefereshScope(all beans having @value attribute), Is it similar to server startup.
