Verrrry interesting question, your Highness.

If you measure between the ends of any diameter, then half of the circle is on
one side of those points, and half of it is on the other side of them. You are
measuring the effective resistance of 2 halves of the resistance, in parallel. So
the effective resistance is 1/4 of the conductor's total resistance . . . 2.5 ohms.
