Most recent pardons have been announced in documents labeled "Executive Grant of Clemency", so I don't think "clemency" and "pardons" are as distinct as you're saying.
And while I know you said "usually", I can't help but note that Hunter Biden was pardoned for any federal thing he may have done, anywhere, anytime in the last 10 years. Some of the last-minute pardons were pretty broad as well.
You can see, this was simply a pardon for his existing convictions, no uncharged crimes, not even things related to these crimes.
As a result, he could still be charged with anything they chose not to charge.
As such, your nitpicking was pointless.
