You cannot do it easily *within* the \xymatrix structure,
but you *can* do it afterwards:
\begin{xy}
\xymatrix...{....
.... here's the matrix cells ...
}%
\POS "1,4",\ar@{}"3,5",\ar"3,5"!E-/15pt/*{}
\end{xy}
will draw an arrow from the "1,4" cell (top row, 4th col)
towards the "3,5" (i.e. [ddr] from the source cell)
but finish at a point shifted from where it would normally (!E)
by 15pt back along the arrow's direction.
My variant of your example at
http://www-texdev.ics.mq.edu.au/MAJA/test2.pdf
now shows an example of this.
