You don't do the same moves on an onsight as you do on a redpoint in most cases. The moves you find on the onsight would be harder and generally more static. There are two holds for the right hand higher than that left hand undercut. It seems logical to assume that if you were a lot stronger and trying for an onsight, you would use one of these and reach up more statically with your left hand instead.
It's only a guestimate grade till the route is on-sighted anyways and I doubt it's any less accurate as a guesstimate than all the other E8, 9, 10, 11s out there that have never seen an onsight either.
