No, just remove the front wheel and look at the inside of the
FORK's steering column, from the bottom. The ridges are not very tall and only a few millimeters wide, so you may want to use a flashlight.

Yes, it may have been measured incorrectly. However, your alternative is unlikely. A shell which had been heavily faced, to 68mm width, would have 2mm of adjustable cup protruding beyond the lockring, which this does not. Of course, an English spindle would correct this situation, but it's unlikely that the assembly operator would have taken the time and trouble to get one.
