The numbers were correct, but the A332 is sometimes converted to 357 seats instead of 363 during the summer period, so they can remove 6 seats and place a mid galley area between doors 2L and 2R. Adding or removing these seats doesn't affect the pitch in any way. But they didn't do it last year.
I thought the A313 were 259, not 258. My guess is there could be 20 seats in Club class, not 19, but I'm not sure. It's been a while since I've seen one.
