Unfortunately, that would not match up with the other three panels. The smart engineer should be able to figure out how to satisfy the customer. It is up mostly to public interpretation, as most art is. That is how I see it but I won't deny someone who labels themselves as an engineer could be a con artist in disguise.

One way I see this is how we interpret the glass half full or glass half empty. There are some ways to see it and modify it a little and meaning can take a different more pronounced form. So yeah both can be valid when we isolate the panel as a completely separate meaning over the other three panels. Then we are considering if the label engineer is truth or a lie.
