[meteorite-list] Please explain this terminology.

Remember Mike that all pieces started out as shrapnel once disintegration begins.  Only those the fully tumble lose all their shrapnel features. 

The maelstrom of SA's entry was punctuated buy multiple fragmentation events.  Which as much going on and as busy as the sky was I imagine there are a wide range of rare but complicated combinations of features.

It is easy to see how a a roll-over lip could be found on a largely shrapnel piece  especially if any part resembles a shuttlecock/fin stabilized form etc.
