What happens when a string offers no landmark
The other eleven strings all give the eye something. A doubled letter, a doubled digit, in one case a triple. This one gives nothing. Fifty-six characters and not a single place where the same symbol appears twice in a row. Nothing about the format made that happen and nothing prevents it. It is a run of luck across 55 consecutive draws.
The effect on a reader is stronger than it sounds. When people check a long string against another long string, they anchor on repeats first and everything else second. Take the repeats away and there is no natural place to start. The string becomes a uniform texture, and uniform textures are the ones where a substituted character hides best, because there is no rhythm for the substitution to break.
This makes the address a good argument for a habit rather than a check. The habit is that you never compare two of these strings by eye at all. You paste them into something that will tell you whether they are identical, or you copy the one you were given and never produce a second copy to compare against. Any method that depends on a person looking at 56 characters and forming a judgement will fail on this string sooner than on any other in the set.
The second oddity here works the same way. This address carries thirteen digits, tied for the most in the set, and not one of them appears in the first eight characters. So the part a reader looks at hardest is pure letters, while the digits crowd into the middle and the end. Both facts push in the same direction. This is the string to copy rather than to read.
The three zones of this string
Its head is eight letters with no digit. Its middle carries four digits and its final eight one. The digits sit almost entirely outside the part of the string most people actually check.

Questions
Is an address with no doubled characters rarer than the others?
Slightly, but not remarkably. Roughly one string in six of this length would avoid doubling entirely. Finding one in a set of twelve is unsurprising.
Does the absence of repeats make this address safer or less safe?
Neither. The string is no different to software. It only changes how easy a human finds it to check by eye, and the honest answer is that no human should be checking any of these by eye.
