Is this a mistake?

At the beggining of disk 2, you have to get out of the shinra place and everything. But have you noticed that when the "fight" happens between Tifa and the Turk girl, that on the laser it says "Sister Ray." Then later in the game there talking about what they should call the ray and the girl says "Why don’t we call it the Sister Ray?" is this a mistake? I mean it is already named obviosly on the side of it. They all say wow thats a great name when its already named

The entire game is a mistake, so yes, that qualifies as one.

The girl was just stupid.

no its just something that square-enix just missed…

You do know that it was just Sqaure back then, and not Square-Enix?

I noticed that 2 on my 2nd playthrough. I thought it was something to do with the translation(They got lazy and figured it was called that later in the game then they would just use that name sooner.
