Why 2metres/6 feet?
Because they had to specify a number due to the fact that too many people don't understand how viruses get transmitted and find it easier to just obey and obsess about one or 2 rules. Did you not wonder why we suddenly sold out of hand sanitiser and soap at the beginning of the lock-down? It was because millions of people who previously washed their hands maybe once per day, suddenly realised that they needed to do it 10-15 times per day. Yes, all those people whose hands you were shaking prior to lock-down had NOT washed their hands after using the loo and were wiping their ick onto your hands. The 2 metre rule is irrelevant w.r.t airborne transmission if everyone is wearing a mask but you still need to stop people from touching each other so it's easier to keep it in place as most of us don't have 1 metre long arms. Amazon have a history of combining people and tech to improve efficiency. In this case they are doing it to reduce staff sickness, so are benefiting both their efficiency AND their staff.
