Is having multiple addresses valid for a tns entry?

A client provided this to me and initailly looked invalid

alias =
  (DESCRIPTION =
    (ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.5.141.22)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.5.141.22)(PORT = 1526))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.5.41.34)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.5.41.34)(PORT = 1526))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.5.41.36)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.5.41.36)(PORT = 1526))
    )
    (CONNECT_DATA = (SID = name)(SERVER = DEDICATED))   )

>From initial testing, if the first server is not avaliable the entire connect fails. Personally Ive never seen this and from checking my reference, this does NOT seem to be valid

Any input would be most welcome

Thanks!
bob
