I don't know the answer to your question, but it brings to mind something that is beside the matter, so if you don't mind: I saw in the 1980's a film of european missionaries in Africa, there the africans were wearing exactly similar red protection cords that you get in tibetan tantric initiations. The converted africans had to burn these protection cords in an open fire, they seemed slightly uncertain and maybe even afraid, when they ran quickly to the fire, took away their red cords and threw them into the fire.
There is an article by David Templeman, where he describes the late indian tantric buddhism, at around 1500's, he says the indian tantric Buddhaguptanath went to San Lorenzo in Madagaskar, where he met local tantric monks and he heard the complete explanations to Hevajra tantra there !!!
