Are you talking about the part where Nel is questioning him about walking "onto" the balcony? That's as far as I've gotten, but I haven't heard OP say that he wasn't there when the bail aff was written or any of that?
If that's the issue you're talking about - I would say he should have been more accurate with his wording so as not to give a misleading impression that he was on the balcony. However, I do not equate this with Mrs Stipp giving a statement that she saw someone in the window when she didn't see such a thing.
But maybe there's more about the affidavit that I haven't gotten to yet.
