Both seem to describe how how receptive a material is to developing a magnetic field when in the presence of a magnetic field.

Your suspicion that both terms describe the same thing is correct. There
is no essential difference. Some people prefer one term to the other,
probably related to whether they approach the subject from a math
perspective or a physics/engineering perspective. But there is actually
a bit of a growing movement to combine the terms under one definition.
As always, the problem with this kind of thing is getting everyone
to actually go along with the change.
