What is the difference between Entered Context and Current Context?

[Amaranth F]

I found that sometimes the current has a value but the entered is empty, so what is the difference?

Thanks.

The entered context is the last context you, the embedder, explicitly
entered with context->Enter or through an instance of Context::Scope.

The current context changes implicitly when a function calls a
function from another context (and changes back when that function
returns.)

OK I see. Thank you!
