It can legitimately happen if, for example, truck delivers material from deconstruction or from storage, which will be deconstructed. Mb there are another such cases.

If this another storage will be deconstructed, but still has some material inside. In that case that material (even if it is only 1 piece) will be transported away
OK. So, partial load from a storage to another storage only when the source storage is being deconstructed. In non-deconstruction case, full load storage to storage. Correct?
