I thought it was obvious, I was using the phrase re-cast as a short hand for spells that grant the ability to take an action (or bonus action) to repeat the original effect or take a related action. There are lots of spells like that for example, Moonbeam, Call Lightning, Sunbeam, The Investures, Hex, Hinter's Mark, Flaming Sphere, Flaming Blade, and plenty more.

The idea that all of those action options in all of those spells are purely mental (especially when every spell listed above has a V and S component and few pretty much say you doing the same thing you did when you cast the spell), is more illogical than the idea that you are repeating the V and S components when taking the action in question.

On a more general note, the vast majority of actions in the game have components that are Verbal and/or Somatic they just aren't spelled out. In fact the actions don't have any visual or audible tells tend to be more explicit on that fact. So assuming all actions granted by spells fall into the latter category is also pretty incongruous with the larger rule set.
