The blocky tip of the arrow is not caused by an overlap of the tip of one arrow with the end of the other arrow. It is simply caused by increasing the thickness as you did. To see this is so look at the output of
Show[Graphics[{AbsoluteThickness[10], Arrow[{1, 1}, {3, 1}]}]]
where only one arrow is drawn.
If you need thick arrows and don't like the way they are drawn by the package Graphics`Arrow` you can always write your own arrow drawing code using graphic primitives
