This sounds like a rule of thumb. There are enough d.f. to calculate MANOVA in this case. MANOVA may not be preferable to repeated measures ANOVA even if sphericity is violated. With only d.f. per factor the violation will often not be too great (epsilon * 0.5). Often the repeated measures corrections are preferable to MANOVA.
