Two things:

Many meteorites are heterogeneous. When we say Katol is L6 or NWA 869
is L3-6 or Almahata Sitta is an anomalous urelite, these are collective
terms. "Katol" refers to everything that fell that day in India. It
has been classified as L6. However, it is possible (and for Almahata
Sitta, probable) that a given specimen does not representatively sample
the incoming meteoroid. There is nothing wrong with saying that
Almahata Sitta #25 is dominated by an H5 lithology or that Katol #4(?)
is a metal rich lithology. Good practice would be to assign some kind
of specimen number to each object and publish a catalog, so the world
will always know what you are talking about. I would gladly publish
such specimen tables in the MetBull database, especially if done
systematically.

As for the name question, NomCom would only give a separate name if
there was significant doubt that a specimen was part of the Katol fall.
This has happened before, as with Galim (b) and Zag (b), but it didn't
happen with Almahata Sitta and I don't think there is much doubt in this
case either.
