At first, like you, yes.

But then, after a little while, I realized that it might be appropriate.

If I understand the system. :-)

Here's what I mean: we've more or less reached a consensus that 
"Identity" is amorphous and hard to pin down -- so much so that it's 
acceptable to have multiple 'identities' (or, formally now, "Identity 
Profiles"). These can be changed at will by an underlying Entity, who 
may want to have several of them.

Entity, on the other hand, is referring to something that has 
permanence in time -- I'm an Entity, you're an Entity, Google is an 
Entity. The roles they can take change -- an Entity can be a Holder 
and/or an Issuer and/or a Subject -- but the 'Entity' itself is 
supposed to represent a real or virtual *single* object that has 
persistence.

Thus, it might be good to have those two different words -- and we 
have them in the right places.

The 'Identity' can change (as part of the changing Profiles, with a 
variable selection of Credentials).

The Entity, in contrast doesn't change (the same Credentials are 
always defined relative to the same Entity).
