Migratory Herders checks which lands match (i.e., non-Mining lands) after the Build Step is over. Builds in the non-Mining Lands might turn them into Mining Lands before Towns are Gathered, reducing the number of lands where Migratory Herders does anything. The list of lands that will be Gathered into is fixed at this point, before any Gathers happen.
However, which lands can be gathered from, the lands that don't match (i.e., Mining lands) is checked when actually Gathering the Town, so it's possible to Gather a Town into a non-Mining land to turn that land into a Mining land, and then Gather that Town into the next non-Mining land.
