I am glad to hear that. Yes, the variable binding mechanism in SPARQLMotion could require a face lift. I thought about adding a mechanism in which the modules (both visually and in the model) would explicitly connect those variables that are passed from one script to the next (such as ?url -> sml:url in your case). And then there is also an open problem with inline variables and URIs, which is now high on my list to fix.
