So, can this be considered fourth_wall?

Not really. They're saying "the men are watching from the opposite shore" - that's actually maintaining the 4th wall, not breaking it. If they said "Look at that guy sitting at his PC watching us" that would be breaking it.

"From the opposite shore" does mean "beyond the 4th wall", though. It's a figure of speech.
