I was curious enough to fact check this. The statue does look like two horses wrestling or even mounting two men, but here’s what the city’s tourism website says about it:

[the famous sculptor Toma Rosandić] named this composition of bronze horses and their tamers “Black horses at play, and with them great heroes”, saying that the horses represent strength, and men tame and control that strength.

I wasn't trying to imply that my interpretation of the art is the correct one.

It's just what I think of every time I see those statues.

It’s a valid interpretation. Fact checking may be the wrong word choice and if it wasn’t clear your story passed the fact check: there are indeed two statues, just like you described (with some margin for interpretation). I was just curious to see this postmodern sounding piece of art and it turned out to be a pair of fairly traditional bronze statues.
