In your example both would work the same. When you are using route maps to
change metrics, for example BGP weight, you will find a difference.

route-map Interfaces permit 10
match interface L0 L1 L2 L3 L4
set weight 200

L0-4 will be assigned a BGP weight of 200

route-map Interfaces permit 10
match interface L0 L1
set weight 500
route-map Interfaces permit 20
match interface L2 L3
set weight 300

L0,L1 will have weight of 500. L2, L3 will have weight of 300.

BTW, they won't let you bring your Bat utility belt into the lab :-)

Can you use this command to identify multiple interfaces

Example:
route-map INTERFACES permit 10
  match interface Loopback0 Ethernet0

or do you need to do:

route-map INTERFACES permit 10
  match interface Loopback0
route-map INTERFACES permit 20
  match interface Ethernet0
