I'll give a slightly different take on this one. *IMO*, claying and polishing are two different procedures that accomplish two different things.
Claying pulls contaminants out of and OFF of, the paint. For instance, it'll pull rail dust out like pulling a splinter out of your skin, but it will also clean off tar and tree sap (something I use it for with most every wash).
Polishing works primarily through abrasive action. SOME polishes also contain chemical cleaners (and there are some nonabrasive "pure polishes" that *I* would call glazes), but GENERALLY, polishes clean by abrading off some of whatever they're rubbed against (usually paint- they remove some paint and also whatever's on it).
The big reason to use polishes is to remove marring and/or oxidation. If your paint is just a little dirty (after washing and claying), something that cleans primarily through chemical means (like AIO) can clean it up. VM is sorta in this category too, although it does contain (very) fine abrasives.
If you're concerned about clay residue, one of these virtually-non-abrasive polishes/paint cleaners (like your VM) will work fine. But *I* never seem to get any clay residue that needs cleaned off. Honestly can't remember the last time, except for when I clayed the backs of some wheels. Used to get it now and then when I used Griot's clay, but only when I used wash solution as lube. NEVER got it with the Autopia Block. Maybe I've just gotten the hang of claying, having gone through *MANY* bars of clay over the years (I've already gone through a Mother's and half of an Autopia Block this year).
