Hmmm..
If you compare the straight-in minima on the old plate they are the same as for a CAT A circling minima (1640'). This is removed on the new plate and the CAT A minimum is increased to 1750'. The vertical profile does continue to descend but only just beyond about 4.5D which could be close to 1750 (the profile box gives an altitude of 1830 at 5D). Then it indicates a Missed approach climb at 1.5D.
I would interpret this plate to mean the following:
You can follow the profile to the relevant MDA for your category of aircraft. If visual then, you may continue descent.
If not visual, you may fly level until becoming visual or reaching the MAP (whichever comes first).
If visual at MAP you will be too high to land so you may opt to circle to land visually.
Or is that completely wrong?
