AD8099 schematics

Hello to everybody.

I am about to use the AD8099 in a low noise integrator.  High bandwidth is really needed and 10 V supply too.

This is the best option I found.

Looking at the datasheet, I have troubles understanding the low voltage biasing scheme.

At a first glance, it looks pretty standart but looking at figure 59 for instance, I do not really get why the decoupling caps on the positive rail (C2 and C3 in Fig 59)  are connected to the negative rail. I would expect them to be connected to the ground. Is there something I miss ?

Best regards
