      I think the problem is that there is probably a difference between when
      you anchor a frame to text




No, that's not the case. But you could take out the "if (myFrames..." line and see what happens:

#target indesign;

myPages = app.activeDocument.pages; 
for (i = 0; i < myPages.length; i++) 
  { 
  myFrames = myPages[i].allPageItems; 
  for (j = myFrames.length-1; j > -1; j--) 
    { 
    try 
      { 
      gb = myFrames[j].geometricBounds; 
      myFrames[j].duplicate ([gb[1],gb[0]]); 
      myFrames[j].remove(); 
      } 
    catch(_){} 
    } 
  }

PS: Which InDesign version do you use?
