It is likely that the import fails in the latest version of the BlenderBIM Add-on because there are a few bugs in the last release that I missed. The next release should work 
Correct, your CYPECAD and ArchiCAD exports are slightly different. CYPECAD contains a profile coordinate offset, but ArchiCAD does not. This is what causes the perceived ObjectPlacement of the column in CYPECAD to be in the corner, but to be in the center in ArchiCAD.
It looks as though you are correct that ArchiCAD does not export that relationship.
