I think even if the anchor type is as-char, the intention is to maintain
that the draw format (shape) and its fly format (text frame) has the
same anchor position. We can't have as-char as the anchor type for both,
but normally we import the shape with as-char and a certain anchor
position, then we can have the fly format with to-char and the same
anchor position.

I can't think of a situation off the top of my head where it's correct
that the two formats would have SwFormatAnchors that point to a
different SwPosition.
