Well, basically there is the impression that he's not very happy to talk about X and its members. That is, he seems to still reminisce about the past until he left X but what comes after that he doesn't wanna have to do anything with. Kinda like 'i'm done with it'. He doesn't even follow what they're doing recently.
Some of us were kinda shocked about what he said in
this interview and speculated about whether it was just a matter of interpretation from japanese to english or whether he really meant it like this. We discussed about it
here.
It looks like he's still somehow hurt about what happened 18 years ago, but come to think of it, he attended the 13th hide memorial such as the X members did and who knows, maybe there's a little chance that he happened to talk to the X members again.
If that also applies to the day he talked about in his blog - that only know Taiji and his 'old friends' alone, though.
