Route Reflector break my split horizon rule

Hi all
I have a strange issue with BGP configuration:

it seems a route is sent back to its sender, what is inconsistent for me

RP/0/0/CPU0:ios#sh bgp neighbor 192.168.2.2 advertised-routes | i 192.168.10.$

====================================================
U can observe 192.168.10.10 is received from 192.168.2.2 and tx back to this neighbor

I precise I am RR, find here the configuration:
