Details:

The positioning algorithm already seems to take in to account the 
"xaxislocation" value somewhat.  If the value is set to "top" then the tick
marks and labels are shown on the top of the plot and the title makes room for
them.  However, an added label for the x-axis is then placed above the axes on
the top, and the title() function does not account for this extra buffer.

Sample code


plot (rand (1,4));
set (gca (), "xaxislocation", "top");
xlabel ("xlabel");
ylabel ("ylabel");
title ("Title overlaps label for x-axis");


which is also attached as file tst_title_overlap.m

The resulting plot is attached as file overlap.png.
