Alcohol does change the surface tension so foaming will be different. Ever seen a security guard shake someone's water bottle to check if it's really water?
The thing that makes beer foam stay there is the protein content. Yeast contributes some, but it's also in the grain. The foam should be less different if you compared something filtered like Heineken and Heineken 0.0.
