`org-element-at-point' and `org-element-context' return information
about the close neighbourhood of point, which is the current section. In
other words, each element at top level within the section get
a nil :parent property.

As a special case, when point is at a headline, each function returns
the parsed headline, without any :parent property defined (it would be
out of the scope of these functions).

If you parse completely the buffer with `org-element-parse-buffer', you
will see that genealogy for property drawer goes like this:

  property-drawer > section > headline > headline > org-data
