You might be. With bars at that height, I'm not.

It's all about compromise. On my Kogswell with bars much higher, the saddle is much more level. Why? Because in a more upright position, my hips are rotated further back. On the Coho, with much lower bars and riding in the drops, my back is flat, hips rotated forward and probably at about the same angle to the plane of the saddle as on your bike.

The force of pedaling is roughly from the BB to your hips- up and back. I've never quite understood the "I'm sliding forward off my saddle" effect for most saddle tilts. Unless I'm sitting upright no-handing down a hill.
