When I redefine a plane, I do not expect the sketch to flip around 180 degrees at the same time...
There are other tools we can use if we want to flip things - redefine-plan is not the right thing for that!
As far as I can tell, there's no way to select the "inside" of a solid face - so it is never the right behaviour to flip based on which side of a face was selected (since there's no way to select the other one when it gets this wrong - but there *are* other ways to flip things if we want to do that).
Alternatively - it would probably be a better idea to add a "flip" checkbox to the redefine plane command:-
It is always better to ask the use which way they want, than to guess and get it wrong 50% of the time (with no way for us to work around that...)
