Ooh. Thank you for writing that out again - I just had a kind of vision/thought looking at the wording again. Both doors open. If looking at it from the front - that is a way of preventing people from seeing things. If that makes sense. An alleged perpetrator could open both doors as a kind of visual barrier fromt the front. While doing something round the back. That would only make sense if the main view was from the front - might be nothing.
