In fact it is guaranteed under XSLT 2.0

Under 1.0 it's guaranteed that the copied element will have copies of all
the original namespace bindings (prefix:uri pairs), so an implementation
would have to be pretty perverse not to use the original prefix, except in
the situation where there is more than one prefix bound to the same URI in
the source document, in which case it might choose a different one.
