At the time that this match took place, Bowser defeating Yoshi was a fairly large shock. The reason for this is simple. Because of that poll, everyone assumed that Yoshi would walk all over his fourpack in the event of Ness not pulling off any upsets. And using that poll wasn't exactly wrong, because people didn't know at the time that those polls weren't very reliable. This caused Yoshi to not only be the board favorite against Bowser, but a lot of people stretched out that poll into saying that Yoshi stood a chance to beat Cloud.
