You should be doing correct.
I found a bug in lxc_driver.c. Could you try the following patch?
diff --git a/src/lxc/lxc_driver.c b/src/lxc/lxc_driver.c
index 2851a2a..018e9f8 100644
--- a/src/lxc/lxc_driver.c
+++ b/src/lxc/lxc_driver.c

}
+ /* Prevent auto-assigned names re-used */
+ parentVeth[0] = '\0';
+ containerVeth[0] = '\0';
}
rc = 0;
