How to interpret a plot where the reference path and sample path are the same?

[byoo]

Could you help understand the plots where the reference path and sample path are the same?

Here's the example of such plot,

This looks to visualize this event. In IGV, I see a small fraction reads evidencing the break but not understanding the AD of "32,31" and how it matches up with the plot.

chr2    95846845        sawfish:0:5054:0:0:0    A       A]chr2:113393726]       999     PASS    SVTYPE=BND;HOMLEN=23;HOMSEQ=CAAAAGCAGAAATAGACAAATTT;MATEID=sawfish:0:5054:0:0:1 GT:GQ:PL:AD     0/1:999:999,0,999:32,31

In addition, I wonder how the reference blocks B, C, D are determined because those blocks don't seem to play a role in this event.
Thank you!
