I hadn’t thought about them as being dye, but yes, that’s definitely true. I generally use them in my sketch journal, when I’m not wanting to mix colors from my travel palettes. Shortcuts! They don’t work well for large washes, because as you point out they have very little pigment on the card. I can imagine what a colorful mess rain on the sheet would make! I keep them on a book ring in a plastic bag, one color family to a ring.
