Yes you get pairs, but that does not mean matter has not been created.
It's not the issue of pairs that is of concern. The bit in your
reference that needs to be considered is this:
This is partly because in a technical sense, you cannot just create matter out of energy: there are various 'conservation laws' of electric charges, the number of leptons (electron-like particles) etc., which means that you can only create matter / anti-matter pairs out of energy.
The tecnical bit it that energy is a description of how much work can be performed, not a substance that can be converted into some other kind of substance.
I don't know why I thought you might have been a troll. It was one of those tingling intangibles. I'm glad it was a false positive on the troll-dar. Welcome to the fray, by the way.

As always. I probably should have said something myself about m being mass, but I get in enough trouble criticizing expressed error to dissuade me from criticizing potential error.
