It's almost always added into the pigment before spraying. I might be wrong, but I have *never* heard of spraying flake alone after the pigmented coat. I have heard of spraying a non metallic base coat then a pigmented metallic coat, but never just flake.
When the machine or person sprays the car they normally lay down 4 layers of paint, the first two are sprayed on with the goal of covering the car in paint, rather than making the metallic flake match. The third coat is applied immediately after and starts to blend the metallic, then the forth coat is a mist with the goal of making the flake even through the cars paint.
It's a little different for single stage metallic, and a little more difficult because you have the added challenge of needing to keep the paint glossy while getting the flake uniform *and* you have the added complication of having your protectant (enamel) mixed in with the paint. With two stage paint you don't need to worry about gloss since you can add clear coats until you're happy with the gloss.
That's why metallic paints are so hard to color match if you need a panel re-painted or something. Not only is there a variance in color due to the paint manufacturer, but there is also the added chance you'll have more/less flake or it won't be evenly distrubted (there are 7 "levels" of flake). So if you ever find a good painter at a shop consider yourself lucky, it's a tough skill to master.

Might most quality paint shops be able to get the SGM paint for repair down the road? Or will there always be difficulty with making ANY metallic paint match up?

They'll be able to do it - to what degree depends on the quality of the shop and the skill of the painter. Most manufacturer's offer a main color for repaints and then a couple alternates, so I woudn't worry about them not being able to find/match the color, the difficulty is just with matching metallic paint in general. If you ever do need a repaint for whatever reason just try to find a quality shop with a painter whose work you've seen.

Or just buy black onyx and have NO worries about match, right!? Of course if they try to put clear coat on their touch up, it won't blend, since the clear coat on Lexus' black is built in right?
