Is that not lift generating > forward motion? If I understand your description, yes, that is correct. However, you're considering a special case, as it were, and not an entire Greenland stroke. Nick was considering the entire stroke, where, for a considerable portion of the stroke, the blade is oriented in such a way as to prevent the lift vector from pointing forward (as it would in a wing paddle). The lift on the blade does exist and generates a force, but it _indirectly_ contributes to the forward motion. With a wing paddle, the lift force is directed forward and thus contributes directly to forward motion.
