The destination operand must be a full four component vector, but the source can be smaller and small sources do not need to be aligned: the offset of the source operand and the swizzle indices are adjusted. The adjustments are done during final statement emission in order to avoid confusing the data flow analyser (and that's when def offsets are known).
