This would mean the part of the stylus that is recognised by the board is in the stylus itself. The core only "expands" the electromagnetic "presence" to the tip.
The supposed button is probably covering the opening where the coil was inserted into the stylus.

Exactly. As far as I know, there's actually nothing in the tip. It's just a plastic nib. The "guts" that trigger the screen are in the stylus itself, and are inserted during the manufacturing process through a hole left in the molding of the stylus body. The "button" is just a plug to fill in that hole afterwards.
Yes, other WACOM stylus do have buttons, but the basic one that comes with the iRex device does not.
That's also why the calibration is so sensitive to the angle you hold the stylus. Since the component that triggers the screen is in the body, not the tip, holding it at different angles will effect where the screen thinks the tip is located. It's important to calibrate it using the exact same position as you do for writing.
