That is a trend on various passports that I have been pointing out. Its evidence IMHO that they are wholly pushing for the public side. A prospective remedy is to file a notice explaining the intent. Alternatively or also to make sure the signature is something like:
Any thumbprint would be over "John" rather than over DOE HENRY JOHN. Or "By: John, as Secured Party/Authorized Representative." Interestingly enough...John for DOE HENRY JOHN
The Chinese passport is rather unique in that it simply states (in mixed case) "Name in full".
