Sulfur before or after oils

Treating plants with oils (such as neem oil) and dusting them with sulfur within a few weeks of each other is apparently a big no-no, due to the chance of phytoxicity. Does anyone know exactly what kind of reaction takes place between the two or why it is phytotoxic? TIA
