The former is odd, but possible. I'd expect him to (find a clever roundabout way to) say "I'm not acutely suicidal right now, but I'm likely to become so. I'll get my affairs in order. Please watch out for me.", given that he talked about depression, but sometimes what you can and can't do is weird.

The latter wouldn't surprise me at all. "If you want to commit suicide, wait a year" is common advice, and if he was able not to immediately choose suicide, he sounded like the type to follow it - reflective, planning ahead, productive enough to make preparations in meantime.
