Rather than just pricing the suite exactly like the room, they instead invoice it at the suite price, with suite price taxes, and then apply a credit to the room account so the final amount you pay is the same as the room price. So, it's treated more like a miscellaneous payment on the account rather than a discount in the suite rate. Below is an oversimplified example, assuming a VAT of 20%, and a room costing 1,000 and a suite costing 2,000.
That method might work out in your favour, if the taxes are recoverable, like for a business stay. But, I imagine nobody would actually use their SNUs on a work stay!
That's if the hotel doesn't screw it up further, and end up awarding a really messed up number of points where you don't know what the heck they did.
What makes it even more annoying is that the base rate when using a SNA is usually
more than the lowest base rate. So you pay more to use the SNA's than what you pay for a base room and yet you get
fewer points than a regular room.
I had this happen to me last year at the Pullman G in Bangkok over two weekends (two, two night stays). I complained to Accor Customer Service and they couldn't understand it even after 8-9 e-mails where I explained it many different ways (though I didn't use a chart like yours, mb I should have). They kept attributing it to a currency conversion problem.

Basically, the agent was looking for a way to say no, insisting that the hotel calculation was correct, even though I got fewer points than when I stayed the week prior (where I was upgraded to a suite without any SNA's). It was clearly a hotel mistake in calculating the base rate when I got fewer points when using the SNA's the 2nd weekend compared to the first weekend when I paid less, did not use SNA's, and got
more points.
I persisted and eventually the customer service agent handed it back to the hotel to respond to. The hotel finally figured it out and correctly re-calculated the points it awarded for my 2nd stay when I used two SNA's. They awarded the points based on the rate I paid for the base room.
