When the thumb drive is mounted by the operating system, a bit is flipped in its metadata (the "dirty bit"). When you eject, the bit is cleared and the drive is unmounted. If you yank it out without ejecting, the bit is left on, and next time you put it in, windows will complain and ask to repair it.

You say it is working fine, but there may be filesystem damage including partially written files, partially allocated blocks, partially deleted stuff, etc.
