you're right, in fact in California state courts it's required to submit a proposed order with a motion.
But no, each judge generally does NOT get to write their own rules of formatting. Districts (at the federal level) go to great lengths to ensure that things are uniform in that jurisdiction, for the ease of the clerk's office. Someone looking at this PDF would likely not immediately know it was an order. State courts are even more uniform, with statewide rules on typeface, font size, margin width, whether something must or can be included in a single document or broken out into a separate filing, number of lines of empty space at the top of a page, etc etc
