Bullshit. There's so much that objectively deficient about that piece of code that I'm having trouble taking you seriously. If that comes at all close to being a representative sample of someone trying to make clear, readable code in that language, then the language was clearly deliberately designed to have an excess of visual noise. But I suspect you're not actually trying to make that code look as clean as the language allows.
The semicolons serve no apparent purpose. Having labels like x01 and x01a with no functional relationship between those lines is outright hostile to the reader. Using x as the prefix for almost all of your label names and as one of your variables is mildly confusing, especially when most of those lines don't relate to the variable x and don't appear to need labels at all. "output" seems to be a magic variable for which assignment has side effects, but nothing in the syntax differentiates it from any other variable. Grouping all the conditionals together, then grouping all their consequences together forces the reader to jump back and forth between lines more than if you put the consequence of each conditional immediately after the corresponding test (in this instance, your way does have the advantage of making the conditional fall-through pattern more readily apparent, but on the other hand that wouldn't be as necessary if you could use more than one line of code to write a single line of output).
You can claim all you want that aesthetics is subjective, but at the very least you must recognize that visual noise you've trained yourself to ignore is objectively different from code which doesn't have those distractions in the first place.
