Where are those extra map-iwds for in cj-mods?

Hello,

I got another question regarding something about where something is useful for:
I notice that in some several codjumper mods I have extra iwd-files which seem to be for certain maps, but not all maps.
Here is an example of one of the mods:

It's something which often occurs by mods which I used when I was playing on cod4 1.6 so I don't know if that could explain somethings.
Also I have played plenty of maps with that mod back then and I notice there is not a iwd for every map.
When I open any iwd file there is an 'image' folder and when I open that folder I get to see some .iwi files which seem to belong to the map, here is an example when I open the iwd of mp_mystic_v2 in the mod:

I haven't tested yet whether I could still play a map or run a demo of a map which has a iwd in the mod while using the mod but maybe someone could give some more information/explanation about why there are special iwd-maps in some cj-mods.

inb4 thanks,

As far as i remember there were some maps which caused download loops. To prevent that i always put the iwd into the mod folder. Mybe u did that too. Thats all i know about it.

Well, I never knew it would prevent downloadloops so at least I didn't put it in there.
Is there a possibility that the person who put the mod in the server put those iwds there so whenever I join the server and the server compares what files are in the mod I have and it sees that I don't have (certain) iwds that it forces me to donwload them? (sort of like a dropbox effect but then when you connect to the server)

I don't think it works like that, because my mod folder has no map iwds at all

I am pretty sure I never put them in myself though xDD
