Mark: I think Maru is talking about the distinction between record/replay mocking and action/assertion mocking.
In record/replay mocking (e.g., mox) you define the expected behavior *before* executing the code under test (i.e., "I expect A, B, and C to happen, now go execute the code under test"), and in action/assertion mocking (e.g. mock), you check assertions *after* executing the code under test (i.e., "Go execute the code under test. Now check: did A, B, C, happen")?
