Hi!
Interesting question.
The second fetter is also translated as "skepticism" or I would say "doubt about the dhamma". Because a stream enterer directly has seen the no-self, there would be no doubt about the words of the Buddha anymore. However, doubt about other things -like ones own capacities- are not included in this and can than still arise. By this reasoning, I don't think a SE has removed one of the 5 hindrances in meditation forever.
