That is a documented behavior:

       --preserve-buildplace
              Do not clean the --buildplace if it has the same contents as the
              .tar.gz file, and no modifications are done.

              For  preserving  the  build place for create and update targets,
              see --debug option.

              As with --no-targz, suppresses appending pbuilder's  process  ID
              to the --buildplace.

              This is useful if you want to attempt to build a large number of
              packages successively, but you expect that many of  them  cannot
              have their build dependencies satisfied.

              It will clean up the build place on failure, or after a success-
              ful build.
