I think that's normal. Kind of simplified script. Anytime we interrogate Sentinels for Intel (doing Fraction's missions) or ask people about details (people who share info about the world) or ask people/interrogate Sentinels about "Orange side missions" they reply only with generic sentence which would finish the whole conversation if there was full one. After 200h+ of playing and most of any available missions done I've found out that only very few times there was something of longer dialogue when interrogating someone or asking for details - like really very few.
