The "CAVEAT" section in the git-svn manual already contains some text about
your case:

       If you do merge, note the following rule: git svn dcommit will attempt
       to commit on top of the SVN commit named in

           git log --grep=^git-svn-id: --first-parent -1

       You must therefore ensure that the most recent commit of the branch you
       want to dcommit to is the first parent of the merge. Chaos will ensue
       otherwise, especially if the first parent is an older commit on the
       same SVN branch.

The paragraphs before these lines give more reasons to avoid a non-linear
history in SVN branches.
