Higher mortality rate generally means lower transmission since the infected don't live long enough to pass it along. If it mutates to be less fatal then I'll be more worried.
They tend to correlate but a virus can easily be both deadly and transmissive. R value is really the only thing to watch here, until a large population is sick we don't really know the impact anyways.
In most species, bird flu is both highly infectious and very deadly. A disease being very infectious can make up for its lethality
