Isn't the pattern on the shutter still required for the type of metering that you describe? At speeds higher than the sync speed the
meter needs to decide to release the second curtain while the first is
still moving. At a very high speed, where the slit is narrow, most of
the patterned shutter will still be visible to the meter cell at that
moment.
On the LX at least, OTF metering only works at slower than X speed anyway.
