Gaining The Advantage

Quick question. If the Daily Mail's panel of 5 managerial experts [1] all believe that Arsenal would rather have been 1-0 down than down to 10 men after 20 minutes, then doesn't it follow that allowing the goal to stand would not have been playing the advantage ? And thus, the referee made the right decision ?

[1] Bryan Robson, David O'Leary, David Pleat, Dave Bassett and Graham Taylor. Was Steve Bruce not available ?
