That's interesting, in the sense that it might explain a software failure, but it doesn't really explain why this wasn't failsafe anyway (given the possibility of a non-flashed ECU failing) nor why remote access was possible. I guess something doesn't add up here.

The safety guarantee from the software could be compromised by an unauthorized modification. Personally I don't like trusting safety systems entirely to software, but I could see it being a decision a big corporation makes to simplify manufacturing (cut costs).
