A straightforward calculation reveals the essentially nonlocal character ofthe leading heavy $Q\bar{Q}$ interaction arising from nonperturbative gluonfield correlations in the model of a fluctuating QCD vacuum. In light of thisquarkonium spin splitting ratio predictions which have supported the scalarconfinement ansatz are reconsidered as a specific example of possibleconsequences for spectroscopy.Comment: Latex, 9 page
