At least that's how I've always seen it used, as a pejorative for conservatives who are (presumably falsely) claiming centrism.
That's abusing the terminology a little bit, but used as a slur against a "centrist Republican" I guess it gets the point across. I see "So-and-so insufficiently conservative Republican is so far to the left, he may as well be a Democrat." That's pretty much the same thing.
Normally the position refers to someone who is a little to the left on economic issues and pretty far to the left on social issues. Think about where Hillary Clinton falls, compared to Elizabeth Warren on the left and Ted Cruz on the right.
