I mean, yes, but when we take irrationality into account, we can't discount the irrationality of saying "if it's suicide, it's not me" to a friend, and then committing suicide right after.
My point isn't about what he supposedly did made sense or not, but what he did was completely useless if true, and even debating it is useless now because of the way it was done. That's why I mentioned how he cursed his friend with that.
