I think he's thinking of the following:
Page 28:
If the unit has not moved, models armed with rapid fire weapons may instead fire one shot at targets over 12" away, up to the weapons' maximum range.
Page 29:
If a unit moves then it cannot shoot heavy weapons - they either move or shoot, but not both.
Neither of these rules specify the Movement phase - they just say "moved." However, look at page 27:
All weapons are classified as either Rapid Fire, Pistol, Assault, Heavy or Ordnance. These rules (found overleaf) are a measure of the weapon's portability and affect the way it can be fired in relation to the model's movement during that turn's Movement phase (emphasis added).
So the rulebook does specifically mention the Movement phase, even though the way you get there is a little convoluted.
