I'm sure you're right, but I think it would also be difficult for them to enforce if they couldn't produce a signed contract. If I were planning on, say, using trade secrets from my current employer to start a direct competitor stealing their biggest customers, then yeah I'm sure it wouldn't hold up in court - but I'm not going to do that.
