Typo. Bill meant to write simple past (watched) would be better

It would really help to know the purpose of the past perfect in these sentences.
Why not 'She watched a video after the children had gone to bed', if the author insists on perfect forms?
What's wrong with 'He has gone to New York after finishing (dropping out of?) school' or simply 'He went to New York after school'?
