Hard to say, but when observing this picture from above, I can't say that both galaxies were forming a bigger or more dense one before.

By the direction of their spiral, it gives the impression of opposite motion and it appears that they are colliding.

But the article is right in one thing, that the illusions created by this "static photograph" might causes a wrong interpretation.
