if this is a bridged call you will get one on each leg as the dtmf passes from one leg to the other.
if in some cases the dtmf is intercepted by something like the bind_meta_app then you may only see 1.

I do indeed look for the Event-Name attribute. But since for a single DTMF digit two events are received from Freeswitch (with Event-Name: DTMF) , i need to differentiate them somehow such that one is processed and the other ignored. The differentiation pattern i found is the channel state (CS_EXCHANGE_MEDIA or CS_EXECUTE state). But then, DTMF-star doesn't always have these two states.
