No. ATM need to sign amounts as well,but keep the key in memory. I don't think it's a consequence of swipe vs chip or anything. It just the UX built into the machine.
IMHO , consumers find it reassuring that they are asked for a pin AFTER the amount is entered into a swipe machine in a bar (where you are much more likely to be drunk). This kind of a mechanism is very nice when amount is entered by someone else (the retailer/cashier).
At the ATM, you are the only one that enters the amount.
So the pin entry at the end of the workflow is not a bug..It's a feature.
