Nobody owns the definition of split....as for confusing hams they are
only confused because they refuse to learn.
#1 Rigs have a split button -- it lights up. That's split mode -- no
requirement that VFOB be on any different frequency than VFOA. You
can run CW Skimmer on an IC-7300 with VFOA on FM mode to give you
12KHz width for receive and VFOB on CW to transmit -- that's split
mode too and you may be in a CW contest working operators on their
frequency or working a DXpedition in frequency split.
#2 Nobody has ever come up with a simple word to describe the audio
split done in WSJT-X modes. It does follow the tx on 1 and rx on
another in the audio space and does in audio what different
frequencies do so it is just split using another method. You could
shift audio by changing frequency if you wanted to.
#3 This discussion comes up every couple of years and never goes
anywhere other than to educate some people about the audio split.
#4 When you pick "Rig Split" in WSJT-X your rig goes into split mode
-- it doesn't know why you want to do it and that's what some are
arguing is the "why"....it's still split mode as the little light is
lit up. Fake It was done for rigs that didn't handle Rig Split well
and None for rigs that can't do either or don't need either (there are
a few).'
So we have:
#1 Rig split -- hardware -- could be RF or just mode or cross-band
#2 Freq (RF) split -- operations (WSJT-X Fake It)
#3 Audio (AF) split -- software
CW/Phone people use #1 and #2. WSJT-X uses all 3.
A lot of the motivation for Rig Split and Fake It came from people
overdriving their audio and the subsequent harmonics. WA1SXK and I
have been on the warpath for over 3 years helping clean up all these
harmonic generators...it's pretty rare to see them now as we have
contacted hundreds of operators and have a paper on my QRZ page
explaining how to set up your audio to avoid it.

All the online definitions I find for 'split' operation are ;
Split means transmitting on one frequency and listening on another.
referring to your own station, without reference to anyone else.
