Rotate molecules in space and see why mirror-image arrangements can behave differently.

Connectivity fixes the atom graph. The same bonds can still allow more than one three-dimensional arrangement.

Rotate the centre as far as you like: a rotation changes the view, never the configuration. Only reflecting the molecule produces its non-superimposable enantiomer.
The stage uses a tetrahedral centre as a spatial cue. Assigning R/S in a real molecule requires priority rules and a defined viewing orientation; rotation alone is not a full assignment procedure.
