Correct, in general

  | public class DoesntGetRedeployed
  | {
  |    public static Collection staticCollection = ...;
  | }
  | 
  | public class CodeThatGetsRedeployed
  | {
  |    public void doSomethingBeforeRedeploy()
  |    {
  |        DoesntGetRedeployed.add(this);
  |    }
  | 
  |    public void doSomethingAfterRedeploy()
  |    {
  |        Object x = DoesntGetRedeployed.get();
  |        // x instanceof CodeThatGetsRedeployed == false
  |    }
  | }
  | 

Although, I'd be impressed if you could come up with such a situation
WITHIN A TRANSACTION! :-)
