Yes well, tour de force in that meaning could refer to the fireworks being very powerful and at some points shoot up like a tower. Especially towards the finale, the fireworks went up so many all at one time it was like watching two towers of white light and all this bursting around the tops of them. I think the name does make sense if you think about it some what.
I assume they used tour de force because not only does the meaning fit if you think about it, but the name also has that powerful connection, like hearing something named tour de force just sounds like it will be an amazing spectacle.
