Civ5Diplomacy_Responses XML oddities

[gascooker]

In the game's Civ5Diplomacy_Responses XML file there are some duplicate entries. For example lines 509-512 are the same as 513-516:

Spoiler :

<Row LeaderType="GENERIC">
<ResponseType>RESPONSE_GREETING_DENOUNCED_FRIEND_OF_AI</ResponseType>
<Response>TXT_KEY_GENERIC_GREETING_DENOUNCED_FRIEND_OF_AI%</Response>
</Row>
<Row LeaderType="GENERIC">
<ResponseType>RESPONSE_GREETING_DENOUNCED_FRIEND_OF_AI</ResponseType>
<Response>TXT_KEY_GENERIC_GREETING_DENOUNCED_FRIEND_OF_AI%</Response>
</Row>

Is this the sort of thing that could cause crashes/errors in the game, as in my MOD I was intending to remove the duplicates, or are they intended?

I have modded a duplicate of this file, and was wondering whether recreating Fraxis' errors was bad practice, dangerous or irrelevant?

This occurs also on lines 1264-1298, where the code seems odd
