Hydro Lock doesn't actually seize the engine in the majority of scenarios that occur at speed.

The cylinder does not have to become completely filled with oil for the top ring to break, which is what generally happens with #4, or the cylinder will crack/ D chunk.

There's also the possibility that you just fouled the #4 spark plug, because that cylinder sees the most oil and sees it faster than the other cylinders.
