According to your interpretation, "Single-thread" and "Multi-thread" modes are equivalent: > Multi-thread.

Assuming there *is* a difference, I thus believe you are mistaken. Now documentation is ambiguous, I agree. My cautious interpretation says that only "Multi-thread" and "Serialized" modes are safe for serialized accesses from multiple threads (where "Multi-thread" is enough, and "Serialized" does too much). Finally, we don't know which threading mode the OP is using. We don't even know if OP knows about threading modes. This topic may interest him.
