I don't likt it that you are saying that he is a saarloos cross. If you want to know if that is true, if he is a cross with a red saarloos you can do an DNA test for the B locus!
Otherwise don't say he is a cross that way you insult the breeder.
Skittish behaviour you can also find in pure breed CSW, although this should not be the due to the breed standard.
Gossip wil stay Gossip until proven that it is the truth.
