baffled by how merging works

I'm fairly new to svn and I'm trying to get my head around how svn handles branches and merging.  I've done a lot of reading on this, I've been able to work my way through merging changes from TRUNK to a BRANCH but I still do not quite understand it.  If someone could start by explaining what happens in this scenario that would help. First, I used this command to see the differences between my BRANCH and TRUNK   svn diff --summarize --old http://repo/proj/branches/1/  --new http://repo/proj/trunk/ Second, based on the summary, I merged differences from TRUNK into BRANCH and commited the BRANCH. Third, I re-ran the command to see if there were any changes I missed.   svn diff --summarize --old http://repo/proj/branches/1/  --new http://repo/proj/trunk/ To my surprise it gave me the same summary.  After merging the changes into the BRANCH and committing the changes, I expected there to be no changes.  So why does it give me the same summary?
