How does JSBSim handle multiple aircraft interactions under the hood?

Hi all! I have a bit of a simple question which is what I'm wondering how it works under the hood when I instantiate multiple aircraft through several lines of fdm0 = jsbsim.FGFDMExec(None). Is it that the first call will instantiate a sort of global simulator where any subsequent instantiations of fdm1 = jsbsim.FGFDMExec(None), fdm2 = jsbsim.FGFDMExec(None) will initialize the other aircraft within that global simulator? I just want to better visualize in my head what's happening when I initialize several different FDMs in terms of how they would interact.

They would all be independent.

Understood, thanks!
