Correct. If you don't account for that extra couple of inches of port correction, just know that you effective tuning will be a couple Hertz lower than you planned. You could also shorten the port a little bit to keep tuning up. Note that some enclosure design software will take into account the port end correction, so you wouldn't want to change it from whatever length it suggests (although like I said earlier, a couple inches here and there won't make much of a difference).
