I think you're absolutely correct. The order does matter but the amount of pressure on each penalty can change anyway. As you say Maguire at number two had to follow from Belotti who missed so the pressure on him, despite being early in the order, rose significantly.

At the point of choosing the 5 there’s no knowledge of exactly which penalty will have the ultimate importance, what I do know is that if I take the 1st or 2nd penalty my team will shoot again.
You’re attempting to equivocate the pressure of the penalties & it just isn’t there.
Did Maguire faced increased pressure to score as Belotti has missed? Yes but you can also argue he knows they’ve missed one so his miss isn’t critical.
You’re attempting to make this a critique of Maguire when it isn’t. The fact that Maguire handled the Italian miss with a top corner penalty means I want one of Kane or Maguire placed further back.
At 4th & 5th Sancho was taking his thinking Jorginho would score & Saka took his knowing if he misses it’s over - the pressures are not the same.
Maguire did well & took a damn good penalty. On the evidence we got tonight, our 2 best penalty takers went 1st & 2nd, we can allude to what happens in training but we don’t know.
