Except when watching Weiss in the series (not going by the trailers, as once again her abilities seem different), he dashes only seem to go in one direction. She pushes herself in a direction at a fast speed similar to Ruby, but not the same. Ruby probably isn't as skilled at using her Semblance because she is two years younger and was a poor student (according to herself). Most of her skills rely on using her scythe skills and she doesn't really seem fully aware of her own Semblance. If she were as advanced as the others with more training, she could probably move similar to the Flash, being able to run around her enemy and hit them from multiple angles without having to change direction like Weiss would with multiple platforms.

As far as Blake, that section was written before the DVD came out and was never updated when the DVD came out. It was believed that they were after-images, but that was based mostly on the trailer as until her fight with Roman, it wasn't clear how it worked. However Roman is clearly hitting solid images and the commentary helps understand it so I will go and rewrite that section soon.
