I was messing around with litecoin-cli and found some strange behaviour. If I try to validate a segwit bitcoin address, with the litecoin-cli it returns as a valid litecoin address.

Is this the intended behaviour, or is this a bug?

[user@server ~]# bitcoin-cli getnewaddress
13nKR2gooAr6MEZev2NsQ5RjQPHBs4vY8g
[user@server ~]# litecoin-cli validateaddress 13nKR2gooAr6MEZev2NsQ5RjQPHBs4vY8g
{
  "isvalid": false
}
[user@server ~]# bitcoin-cli addwitnessaddress 13nKR2gooAr6MEZev2NsQ5RjQPHBs4vY8g

[user@server ~]# litecoin-cli validateaddress 39kzm57uJi8iZ9qJWGivVjf44XYJFLur9M
{
  "isvalid": true,
  "address": "39kzm57uJi8iZ9qJWGivVjf44XYJFLur9M",
  "scriptPubKey": "xxxxxxxxxxxxxxx",
  "ismine": false,
  "iswatchonly": false,
  "isscript": true
}
