Why in Adapter Object Overview (R3AC1) screen in tab "Initial Flow Contexts" the consumer is CRM, although the target system is R/3 system?

Why in Adapter Object Overview (R3AC1) screen in tab "Initial Flow Contexts" the consumer is CRM, although the target system is R/3 system?

I can understand that when data flow is from R/3 to CRM system the consumer is CRM system. But I could not understand why when data flow is from CRM to R/3 the consumer is still CRM system.
