I am not Joe, but I can answer your question.
In diversity mode, the K3 operates just like a single receiver as far as
the controls are concerned (except for the audio effects attributed to
diversity). In other words, if you are operating SPLIT, you would tune
to the DX station with VFO A and transmit on VFO B. To listen to the
pileup (on your TX frequency VFO B) you would hold the REV button to
listen to the pileup as long as you hold the button, but if you wanted
to not hold the button and switch to hear the pileup, the A/B button can
be used to switch VFOs until you wanted to switch back (with the A/B
button).
Since you have both the mainRX and the subRX, it makes more sense to use
the subRX in its normal mode where you set SPLIT on and listen to the DX
on the subRX while transmitting on the mainRX frequency (the subRX
frequency does not have transmit capability). There are some ways to
reverse this, but I will not go into details, this is the 'fundamentals'
of split operation.
For linked VFOs, imagine you want to work DX operating with a fixed 2
kHz split while the DX station is changing his TX frequencies while
maintaining the 2 kHz split - that does not happen very often (maybe never).
You can set SPLIT on and separate the VFOs by 2 kHz then invoke LINK.
The VFOs will always be 2 kHz apart.
I don't think that situation occurs frequently. The only remote
occasion I can foresee is for the QRP Foxhunts, but the Foxes rarely
will operate SPLIT.
Normally, the DX station stays on the same frequency and you would want
to leave the RX VFO tuned to his frequency while you would want the TX
VFO to tune to either the last station worked or a clear frequency
within the pileup. The current TX VFO is displayed in the K3 or KX3
display by an arrow. Pay attention to that arrow lest the "up cops"
become irritated with your transmissions.
IMHO, the changes made in 5.10 simplify the use of the SUB button. No
more short hold of the button to link the VFOs and no long hold to
enable diversity.
How many times have we seen posts to this reflector saying that the VFOs
track each other. This is a result of the difference between a long
hold and an extra long hold of the SUB button.
Relegating the linked VFOs to a programmable function is a good idea IMHO.

Hi Joe,
I guess there is some confusion then as to the function of Link.
Myself, I thought it was solely there for diversity mode.
So, how else would one use the Link function? What is its purpose?
Thanks
