It seems unlikely that this is accidentally reading old encrypted data blocks. The filesystem wouldn’t even try to access data that it hasn’t written to yet. So you would need both filesystem bugs and bugs with encryption key management.
I think the theory that iCloud is accidentally restoring images based on the device ID is much more likely. It is also quite concerning but seems more plausible to me.

Offloading the data to the cloud and making it accessible on other devices no longer signed into iCloud.
That is so much worse if true.
