EIGRP over Multilink PPP

Hi Experts,

I have the following two routers connected with two serial links,when i
combined them as logical ppp multilink interface and running eigrp over it, I
always noticed that R9 have eigrp route as the same multilink interface but /32
and VIA R6 multilink interface, but R6 didn't show anything !

Is this relate to how ppp advertises the connected route, as I know it
advertises router's own connected route as /32 both direction NOT one
direction.

R6 10.140.140.0/31
R9 10.140.140.1/31

R6
