| contents | As a straightforward application of the recently calculated two-loop heavy quarkonium Hamiltonian, we evaluate the two-loop $O(ε)$ term of the $1/(mr^2)$ heavy quarkonium potential. Compared to a previous calculation we find a small difference in the coefficient of the maximally non-abelian color factor $C_F C_A^2 $. We further examine this coefficient carefully. |
