Deep strike happens like this:
1) place a model from the unit on the battlefield (this is the 'point') referred to in the mawloc rules.
2) roll for scatter.
3) deploy the unit at this final location
4) if the unit is a mawloc, make its TFtD attacks if there are models in the way that would cause a mishap.
5) if the unit can't be deployed, it mishaps.
The misplaced result picks up at step 3 of the cycle, where as the mawloc's ability applies to step 1, the initial placement. The reference to valid deep strike formation has nothing to do with the mawloc ability, but rather is referring to a unit needing to deploy in b2b, in concentric rings around the initially placed model.
In the misplaced result said, "place a model anywhere on the table ... Without rolling for scatter", I'd agree with you, but it doesn't, it says "deploy the unit anywhere on the table..." which is explicitly different from initial model placement for deep striking.
The long and short of it is that "place" and "deploy" are two separate game terms, and the Mawloc's rule affects placement, not deployment.
