4♠ means whatever South wants it to mean. He has information - RHO opened the bidding 1♣ and, after his 1♠ overcall and partner's "unassuming cuebid", RHO bid 2♥. Now, it would seem that 4♠ would be bid here with the expectation of making 10 tricks with spades as trump. But if the spade bidder had a weak hand with long spades (which he did not preempt with on the first round) and he decided that, based on the auction, 4♠ was the right tactical bid, then so be it.
Can I come up with a hand where it is "right" to bid 4♠ even though you don't think it will make? Not offhand. How would I describe the 4♠ bid at the table if asked? Probably that the bidder expected to make 4♠. But I am just pointing out that it is remotely possible that he doesn't expect to make 4♠ but still thinks that it is the right call to make.
BTW, the dictionary definition of "unassuming" is "modest: acting in a way that does not assume superiority." So partner's cue bid is a modest bid, not looking to toot his own horn, just playing along with partner, seeing what he wants to do. Really, that is a fun name for a bridge call, but most unlike most bridge players.
Me and P weren't sure if this was showing a genuinely good hand or pre-emptive
