An aspect leaves an influence but in a relationship, planets exert influence on each other.

Let us assume Moon is being aspected by Saturn, Saturn leaves an influence on the moon but does not take any from it.

In situation two this Saturn is related to Mars, so when Saturn aspects the moon in this scenario it will also carry the influence of Mars it has soaked by being related to it when it aspects Moon in this situation.
