".3." is an emoticon. It's around the same length, yes, but we don't know when it's going to be translated (and, like I said, if it's part of the DX1 compilation he might just leave it to Zero-san to translate once it's out). Others have helped translate DxD in the past (such as volumes 7 and 9) and you can't tell the difference.
