If you click and drag the first helper; the current object or the currently selected set of objects would get dragged.

There is a more precise way to drag an object: When ending the drag; you should drop the mouse right on top of the architect . If that be the case, then the object (or selected objects) would get precisely shifted to the location of the architect.

By precise; I mean that TAD determines where the first helper used to be located; and then displaces the object/s in such a manner that the first helper would potentially be exactly on the architect

To locate the architect precisely; use the Headsup commandline
