"Anyhow - anyone know if it is true. I find it quite odd if it is!"

They won't. Things that seem different scare them (read make them very wary). They also have a keen sense of smell, and anything that has 'human' on it will frighten then off. They are almost impossible to trap because of their wariness. One of the better books to read to understand wolf behaviour is Mowat's novel, "Never Cry Wolf". It was based on a biology study and despite being a novel is quite accurate as to the social lives of wolves. It also describes well their 'bush' skills and hunting behaviour.
