I find this amusing since there are several lines like that. Most recently in the last volume. But, there are numerous lines one could found throughout the books.
If you simply look at his behavior in the first place, it's not normal. I have a brother and a sister and I know, his mentality concerning his sister is way different to whats normal. So really, the more important argument to make is what does "sisterly love" mean to Tatsuya himself, especially considering that he's able to be aroused by Miyuki in that way.
