I believe you, I just don't understand why

I vaguely recall that it's because zic recognizes this situation specially, and refuses to create the two hour-apart transitions that the rules would require if applied strictly. Instead, it merges the transitions in the common-sense way. zdump isn't the program that makes this decision; it's zic. zdump merely reports what zic did. If my recollection is correct, ancient versions of zic didn't do that, and this caused several problems. I don't remember offhand when this got changed. I suppose it couldn't hurt to document this in the zic man page, if someone wanted to volunteer to do that....
