NCAA-W, correctable or not?

[Scrapper1]

This actually happened in the women's game before my game tonight.

A1 is fouled by B1 and is awarded a 1-and-1. B1 makes uncomplimentary comments to the official, and is assessed a technical foul. Officials clear the lane and administer the first free throw of the 1-and-1, which is successful. They then realize that they should've administered the technical free throws first.

So they wipe off the first free throw, and essentially start the sequence over in the correct order.

First, is this a correctable error?

Second, I seem to remember that there was an AR on the women's side that treated a similar situation (or maybe it actually was this situation) as a correctable error, even though it seemed to me that it was not really correctable. Anybody know what I'm talking about?

Third, what would've happened if the first free throw of the 1-and-1 had been unsuccessful? Does that change anything?
