A straightforward calculation reveals the essentially nonlocal character of the leading heavy Q¯Q interaction arising from nonperturbative gluon field correlations in the model of a fluctuating QCD vacuum. In light of this quarkonium spin splitting ratio predictions which have supported the scalar confinement ansatz are reconsidered as a specific example of possible conse- quences for spectroscopy.
