The monster logic certainly is not very intelligent. They will repeatedly cast the same spell. In some circumstances, this is a good thing. In the case you describe, each flame object does some amount of damage, so having got hit by 6 of them will do more damage than just getting hit by one. In other cases, this may make less since. If the character is already paralyzed, probably better to hit them with a lightning bolt or fireball and not another paralyze. The spells do not currently merge. There is some debate on how much good it will really do to let them merge (let them in this case means that all the spell parameters match up). The main question is how many spells can actually merge in that situation. Because in the case of the multilple spells, they will be in different phases of the duration (so for example, if you cast burning hands, wait a tick and cast another such that it is effectively one space behind the other, nothing in that will really be able to merge even though the effects are overlapping, and this is because the duration of the lead is a little shorter than the one behind.) Similarly, things like damage, direction its moving, and other things may very well be different.
