The temporary directory prepared by "difftool --dir-diff" to show the result of a change can be modified by the user via the tree diff program, and we try hard not to lose changes to them after tree diff program returns to us. However, the set of files to be copied back is computed differently between --symlinks and --no-symlinks modes. The former checks all paths that start out as identical to the working tree file, while the latter checks paths that already had a local modification in the working tree, allowing changes made in the tree diff program to paths that did not have any local change to be lost.
