Right. The first example on the site shows disease as a cause, and death as an effect. This is wrong on several levels: There is no such thing as healthy or sick. You’re always fighting off something, it just becomes obvious sometimes. Also, a disease doesn’t necessarily lead to death, obviously.
Since you're always going to die, the problem is solved - the implication is true by the right side always being true, and the left side doesn't matter.
