No, that isn’t possible sorry.  You can however batch process 2 presets in the same batch.  You would then get 2 crops for each image and you would need to remove the ones you don’t want.

Honestly though, I think the easiest way would be to first sort he folder by image dimensions.  I know in Windows you can add dimensions as a column and sort by it, not sure on Mac. Then after they are sorted you can move all of the landscape into it’s own folder. Then you would have to run 2 batches.  I think this would be easier than removing the unwanted images afterwards.
