Maybe that a point-counter would bid 4♠. If you play strong NT's, 3♠ is fine. However, if 3♠ can contain 15-17 bal., I'd bid 4♠. Point counter? What, 3+18=21, so pass? I assume, that this time you are only pretending to be silly? Hyperbole, again. But, since partner will stretch to keep the auction alive with a King, the "point" is that point-counters should bid 3♠, because 18+8=26, and Responder raises with 8-9 from a 6-9 range, so how would point counters bid this differently? But they will bid 4♠.
