WHY capacity has been reduced from 265 to 201.

38 millenniums at 7 across takes considerably less floor space than 30 Skybeds at 6 across. They will lose a lot more than just a few rows of Y to fit the Skybeds in.
On the A330-300, 5 rows of Skybeds fills the front section of the aircraft between doors 1 and 2. However, on the A330-200, that section is about 30% shorter, so assume they can only fit 3 rows and perhaps a toilet and galley, thus needing a further two rows of skybeds after door 2. Thus reducing Y to around 200 seats.
See
this image from Airbus, and look at the example 3-class config. if 3 rows of Skybeds fir between doors 1 and 2, and 2 more rows behind door 2, the J will take about the space shown for F and J in the image.
