Isn't the most obvious candidate for the difference that these are two separate polities? The mock election was not limited to Londoners. I would expect their voting habits to be different, just as I would not be shocked to find DC Metro area voters to behave differently than US voters as a whole. Not saying that is the only explanation, but at least an obvious line of inquiry.
