BGP Route-Map Incoming Updates

I was going through with one document and found below statement:

*When using the match ip address command in BGP, you can use route maps only
to filter outbound updates.
The use of a match ip address route map is not supported on inbound BGP
updates.*
**
somehow i failed to understand this statement and tried on lab with 2
routers .
Match ip address within route map provide options as below:

+++++++++++++++
Router(config-route-map)#match ip address ?
  <1-199> IP access-list number
  <1300-2699> IP access-list number (expanded range)
  WORD IP access-list name
  prefix-list Match entries of prefix-lists
  <cr>
Router(config-route-map)#match ip address
+++++++++++++++

+) match ip address is able to filter inbound bgp updates .(tried with
prefix list and access-list)

can somebody explain it in detail for me ???

Thanks
