Reintegrate Merge causing tree conflicts after revert?

Hello,

--- PROBLEM
Using the --reintegrate option, merging the same two branches twice
(from reverting 3 merged files after the first merge) causes many
non-existent tree conflicts, along with text conflicts, after the
second merge.

--- DESCRIPTION
I had to merge branch A into branch B.

So, I checked out B, then ran svn merge --reintegrate A B. This worked well.

However, I didn't want the last 3 check-ins from A to be in B.

So, I ran svn revert on those few files that I didn't want merged in,
then checked in B back into svn. So far, so good, right?

I then wanted to merge those few files from A back into B. So, I
checked out B again (which had all of A except for those 3 files), and
re-ran svn merge --reintegrate A B.

I naturally expected to only see the modification of those 3 files,
however I instead got 13 tree conflicts, and 4 text conflicts. Why?

--- STEPS
(Assuming REPO="your://svn/url")
1) svn co $REPO/branch/B
2) svn merge --reintegrate $REPO/branch/A B
3) svn revert path/to/file1
4) Repeat step 3 (for clarity) twice for file2 and file3
5) svn ci B -m "Merged A into B"
6) rm -rf B
7) svn co $REPO/branch/B
8) svn merge --reintegrate $REPO/branch/A B
9) Enjoy the "Tree Conflict Show"
