I'll admit to have got used to the
K-70,
KP etc. lighting up the focus square that it's using, but, as far as I've been able to ascertain, a lit square doesn't equate to a focus lock, just to where the camera is trying to focus … it's the "green hexagon" at the bottom of the screen that confirms lock, which seems to be how the
K-3iii works and indeed how the
*istDL2 (which doesn't have focus points) works, so it's a concept I've got used to.
On a reasonably static subject, the one more or less equates to the other, so might be misleading, but tracking a bird against a clear sky with my
KP using AFC and multi-point focus, it can become reasonably obvious that the red squares are flickering on and off, but the green hexagon isn't lighting … when it does is the time to press the shutter
Inevitably - YMMV
