The indicated frequency on a counter will not change as you are
transmitting a 50Hz wide signal within a frequency range defined by the
upper sideband width. The position of your 50Hz wide transmission will
vary within that sideband width but you will need a good spectrum
analyser to see it.

Same way you tune your transmitter by moving red marker.
*No, The green marker is just a decode filter for that mark to place
that traffic in the right pane for view.****The receive frequency covers the whole 3 -4 KHz bandwidth of your pan
as set. ****See the left pane for all of these signals.Regardless of your TX
slot, you will be still receiving there*
If you have
"hold TX freq" checked you and set your TX where ever you want over the
(audio) IF.
In that case you will have a split qso where you transmit on different
frequency as you receive.
*No because you receive also wherever that TX marker is. The green
marker is not a RX tune, but a decode filter.****Your receive all of the pan, not just the green marker slot*
"Split operation" in settings has nothing to do with this. It is
wsjt-x's "artificial intelligence" to optimize TX audio filter usage, if
user allows it by selecting "rig" or "fake it".
Whether or not this "artificial intelligence" is used it does not change
your RX and TX tuning (red and green markers) on RF spectrum, I.E. does
not cause any "split".
Test with frequency counter. Your TX RFcarrier does not change when
selecting "none", "rig" or "fake it".

*There is no TX RFcarrier as you said earlier, so there is nothing to
see for change, only the usb sideband sum of RF and audio frequency.****However in the radio there is a real ( not artificial ) generation of
CP and audio signals mixed for the result TX ssb signal.******On 20m at 400 TX marker, my FTDX101MP in 'rig split' has TX Sub vfo
set (by wsjtx) at 14.072.500, and uses an audio frequency of 1900Hz
(1500 -2000 Hz being the target passband window) ****Sum = 14.074.400, the xxx.400 equating to the the pan indicator.*
*My monitor scope pickup indicates the audio at 1900Hz mean with the
CP frequency at 14.072.500, that are mixed.**The vfo indicates the real CP reference **That is real as the passband filter hardware requires for best signal
quality and level consistency.******Many not using split/fake wonder why their signal strength/quality
varies across the pan in use, and the reason is not 'artificial'*
