Head-first at 60 miles per hour?

One small quirk about our recent trip on the Auto Train: the porter made up our beds with the pillows at the forward end. On every train trip I've taken in the past (excluding the ones in coach of course, and in bedrooms with beds across the width of the train), the pillow was at the rear end of the bed. I was under the impression that there were safety reasons for this--basically you wanted your feet forward so if there was an emergency braking or wreck, you'd be less likely to hit your head travelling and sleeping feet-forward.

Has there been a new study suggesting the old way was wrong? Did our porter make a mistake? Is there something else going on here? I'll be interested in seeing if we return to Florida head-first.
