Of course, you get a 5 year multiple entry visa. I got mine last August from London. Entered September and stayed for 6 months. Spent 3 days in Vietnam in March and got stamped back in no questions asked. Best visa I've ever had.
The ones who've been questioned up to now are some people who got their DTV from Cambodia, Vietnam, Myanmar and Laos. Immigration are suspicious some people used a dodgy agent.
