What meaning is conveyed with the staged Vatican/Pope desk photo-ops?

Assume The Subservient Schoolboy Position Propaganda

This is a topic that's been on my mind for some time. I haven't heard anyone else comment on this Vatican practice of depicting world political and business leaders in a subservient position to the Vatican.

Notice which world leaders below won't comply with 'across the desk schoolboy position' and opt for the staged 'less subservient' side table pose.
