Bike manufacturers have been shifting to long top tube + short stem. It wouldn't surprise if the stock stem also shrank by 20mm, putting the handlebars in exactly the same position. Unfortunately, the spec sheets never mention stem length so it's a toss up.
The other option is that with the slack angle, they lengthed the top tube to keep weight forward. Slack HTA is great for descending, but there's a tendency for the front end to lift/wander on steep climbs. Shifting weight forward helps cut that down.
