Have you considered the fact that it said cards and not monsters? In total there are 7 card slots on each side of the field. Field zone, Spell/Trap zone and the Monster zone. Thus the enemy could have no monsters but have three traps/spells on the field and that would work.
Considering it does indeed check specifically for monsters, no, I did not consider that.
That being said, editing stuff like this is obviously not necessary. And would create a ton of issues if we did get a "Master Duel" mode or something down the line.
