Maybe I need to see a better video, but no, she doesn't seem to be talented in that area.

She's not a dancer at all.

Yes

Both choreographed by the same person.

In the days of The Fame and The Fame Monster she used to be a great dancer, but I guess her body couldn't take so much and she had to settle a bit for what she is now, an ok dancer

Yes.

People who say she can't dance are pressedT.

She is not a professional dancer, but she IS a good dance. She has proven that. On top of that she can serve flawless live vocals while dancing. Not many popstars can pull that off.
