In the paper the term $SPSD$-ring for a semiabsolute and semidistributive ring is used. Let $R$ be the Jackobson radical of Noether reduced $SPSD$-ring $A$. We assume that the set $F(A)$ is nonempty. Then the quiver $Q(A)$ of $A$ is strongly connected. We show that the converse does not hold for Noether $SPSD$-rings.
