PPP encap with no ip unnumbered

Group,

I had the following Q in one of the mock lab.

*R4--s0/1-------------------- s0/1--R5*

1. Configure PPP on serial connection b/n R4 and R5
2. Do not apply IP address directly to R4's interface S0/1.
3. Do not use "ip unnumbered" to accomplish this task.

*My solution was -*

R4:
interface virtual-template1 type serial
  ip address 155.1.45.4 255.255.255.0
  encapsulation ppp
!
interface serial0/1
  no ip address
  encapsulation ppp

R5:
interface s0/1
  ip address 155.1.45.5 255.255.255.0
  encapsulation ppp

*The Mock Lab solution was -*

R4:
interface multilink 1
  ip address 155.1.45.4 255.255.255.0
  encapsulation ppp
!
interface serial0/1
  encapsulation ppp
  ppp multilink group 1

R5:
interface multilink 1
  ip address 155.1.45.5 255.255.255.0
  encapsulation ppp
!
interface serial0/1
  encapsulation ppp
  ppp multilink group 1

Whatz wrong with my solution ? It worked fine and I had no issues running
RIP and BGP on that link.

Regards,
Naveen.
