I suspect it's that those are all "minimum" and it's a long list. I would guess that if you were "at minimums" on every item, you'd not be "ideal", you'd be "barely considered".
What that "OR" allows the company to do, for example, is take a quite experienced TP from another company in the same general classification of aircraft, and not worry "but he didn't graduate from TP school X", as long as he/she has an engineering degree.
It's also saying that a TPS graduate doesn't need an engineering degree. Which seems fair enough, on balance.
Bear in mind also that often it'll be a HR department or recruitment agency doing a first cut at the candidates list, to winnow it down before it gets to someone with "other things to do". The HR type person will apply this list as a bunch of "must have" minimums. So to allow the person actually doing the final selection a chance to apply a bit of judgement, there's a tendency to set them each a little low individually, so the "ideal" candidate with 1 day too little experience doesn't get binned early. (The counterbalance to that is if you set the minimums too low, HR will pass on every Tom, Dick or Jane and you'll be swamped.)
In that sense I'm reminded of the "Viz" advice when filling a vacancy: take half the CVs you receive and throw them straight in the bin, to avoid hiring unlucky people. That's a lot closer to the truth about recruitment to a large organization that many of us would like to think.
