Yes, richandfleur ... I am pretty aware of these problematic things, as you will know.
Because some of us still work with the K7 and K5... and some have postively looked at the old mechanical SR I still posted these tests and prooves.
Some of us always felt that Pentax should open mechanical sensor-SR for video-mode again. Now we see they have closed it for good reasons - even if it was of some help to some of us - if done very aware.
Yes, this is rotten past - but never dies - as we still (and me) have a Pentax K5 or even K7 ... Right ?
Maybe "just for the record" only ... OK ?

There is one situation Steve, where the SR on my K7 surprised me a lot - positively - when shooting from a driving tripod:
(...and your training can sophisticate the SR: >> as commented in here << ...)

My K5 did just the same RETURNMENT with the SR - and I once had two of them in my posession !
Maybe your shootings where not that smoothly and controlled like in my testing-demonstration ?
Also in very slow panning it can be overseen, especially if not so "flatmoving" as in my peacefull scenery above.
The same in very wild situations, when one can miss-out this "bug" because so much is happening for the watcher anyway ...
Of course SR was On here. Only excuse: It may have been broken - other than in your K7 ... >> see also
You can see the function in the always-turning-back to the original-standpoint, which seems to be logical for this kind of sensor shake reduction.
Yesterday I had been in the shop again to do some pannings and focus experiments with the GH5. There was almost no such false returning of
the 5-axis stabilisation - plus two axes on the 12-35 lense - plus electronic stabilisation ... as far as I could see in the viewfinder. I have written the
clips to my own SD-card and will see now what came out of that ...
Yes, there is a little image-turning-back as well ... but that might just be a reflex of my muscle-moves that prevent a full stop here.

Eletronical SR - unusable.
Mechanical SR for video would have to be reinvented by Pentax (besides the copyright of other systems) And there are many companies these days who have a good 5-axis-image stabilisation
Once we liked the mechanical SR by Pentax K7 and K5 a little more - but today it is not acceptable any longer. Going back in time would serve nobody.
In case you haven't seen this example for the old Pentax-mechanical SR start at minute 1:18 (K7 and K5 had the same SR)
