What does # Reads with same position mean? 

I just ran this using the same BAM file for comparison (available at http://www.cs.berkeley.edu/~massie/bams/mouse_chrM.bam -- it's only 12MB). I received the following output...

````
ADAM 1 Reads: 163064
ADAM 2 Reads: 163064
# Reads with same position: 168266
ADAM 1 # Unique Reads: 0
ADAM 2 # Unique Reads: 0
````
There are 5,202 more reads with same position than are in the BAM file? Is that correct?
