Oh dear - every once in a while I make a mistake - not very often, but it does happen occasionally - lol. I haven't received my old passport back yet, but I looked at my husband's which was issued at the same time and you are totally correct - he did sign on a separate page. The first two pages on my new passport are different though - the laminated page is very heavy and printed in black and white,(used to be in color), and the signature page now has a color photo on it. I guess those changes made me think the signature part was different.
