a square peg in a round hole

Remember that toy you use to play with when you were a kid -- the one with the different shaped blocks and the box with different shaped holes that matched? Well in essence, I played a grown-up version of that game today, and I don't think the people who designed the pieces were really communicating well. Because supposedly this cog with its pattern:


is suppose to fit over this hub with this spline pattern:


The pictures are a little out of focus (taken with my phone) but I think it's obvious that, "the shoe doesn't fit" if you know what I mean. What the spline pattern should look like, is something like this:


Instead, the splines are deeper, and at different angles.

Hopefully tomorrow when I call customer support someone can help me understand why my Shimano 9-speed cassette doesn't seem to fit over the hub of my new Easton ea70 rear wheel when ,according to their website (and every other retailer website I've checked), the two are compatible. I must be missing something REALLY obvious here.
