Cannot zip files with the same name?

I could not believe this: it seems that the zip specification does not allow two different files with the same file name going into one zip file.

In my case I use an external file to specify all the files I wanna zip. This could look like this:

../Website1/favicon.ico ../Website2/favicon.ico

and there we are, that's not possible, despite keeping the directory structure. You would expect the name to be <../Website1/favicon.ico> rather than but that does not seem to be the case, I get:

"Invalid ZIP request (cannot repeat names in Zip file)"

with WinZip. I tried the same with 7Zip - same result.

Strangely googling did not show many hits that really fit but those I found seem to confirm my findings. That's hard to believe since this limitation is very severe. I actually struggle to understand why this did not hit me a couple of decades earlier.

Am I overlooking something very basic here?

To be precise:

Adding these two files:

C:\Temp\Website1\FavIcon
C:\Temp\Website2\FavIcon

results in a single file; the last Add wins...

This however:

Website1\FavIcon
Website2\FavIcon

results in a zip file that contains both files.
