Ah! 😁
I had noticed your last post and was musing about it. I think you may be right.
If they're both using the same iTunes Library, then I guess that if you delete a song from one iPod, then when you Sync the other iPod, iTunes will take the songs from the Playlists on the second one and add them to the Library and back to the first iPod... (I guess).
There is a way of managing two iPods in one Library, although it's not something I do and I do use two iPods. I have a Touch and a Classic. Since they serve different purposes for me, I have two user accounts on my computer and each iPod has it's own distinct Library on one account only.
If I do want the songs from (for example) the first iPod's Library on the second iPod, I simply add the songs from the first iPod's users' drive to the second iPod's iTunes Library. So instead of the path to the song being C:\user2\Music\iTunes\... it's C:\user1\Music\iTunes\...
They're frightenly complex things, aren't they? ... but good fun, none-the-less.
