Techniques that are substantially the same are sometimes referred to by different names depending on the style or organization the dojo belongs to.
Variations can even exist from dojo to dojo within a style.
There are also schools that use the English translations, rather than the original Japanese. I've heard that O-Sensei didn't teach the names of techniques, per se, but instead focused more on the movements themselves, so I'm sure there is a great deal of room for interpretation.
