But this is not a loading coil. It is part of the series C, shunt L, L-network
matching network.

Good question, John! I have no idea. But I think the answer might lie in
current distribution. We know, for example, that loading coils at a
low-Z point in the antenna reduce radiation efficiency because it's a
current maxima and inductors don't radiate.
