In a recent paper, Lin, Ruberman and Saveliev proved a splitting formula expressing the Seiberg-Witten invariant $lambda_{SW}(X)$ of a smooth $4$-manifold with rational homology of $S^1 imes S^3$ in terms of the Fr{o}yshov invariant $h(X)$ and a Lefschetz number in reduced monopole Floer homology. In this note we observe that a similar splitting formula holds in reduced instanton Floer homology.
