The Razor suggests that the system with the fewest assumptions, that is also compatible with the known data, is best.
Saying that X is identical to Y is a very strong assertion—it implies a great deal about their full sets of properties. Saying that X is Y is not necessary, given that they are known to share one property. All we can say AND SUPPORT is that X might be Y. The two could easily be distinctly different and still share one property.
The Razor does not indicate that asserting X is Y is justified in this case.
