So, let's look at other three letter words that differ in only one character and see if a reasonable person would find them to be overly similar:
fog - dog. No.
bet - get. No.
top - pop. No.
foo - moo. No.
It's easy to say "oh, they're only one letter different" but when you're talking three letter words, that one letter carries a lot of weight, IMO.
In fact, I'd argue that something like the "macrosoft" / "microsoft" example would be a better example of something that could legitimately be confusing (albeit still a stretch) than "moz" / "doz".
