XBee Schematics - Two caps on VCC pin.

According to the schematics, is a good practice to add two caps on the VCC pin.

This is what is there:

Poor power supply can lead to poor radio performance especially if the supply voltage is not kept within
tolerance or is excessively noisy. To help reduce noise a 1uF and 8.2pF capacitor are recommended to be
placed as near to pin1 on the PCB as possible.

So, those are decoupling caps?

Is this what they are talking about? Pic below.

Thank you.

Yes that is what it is referring to. They are used to filter out any noise on the line that may cause issues with the processor.
