The fact of the matter is that under current storm naming protocols/rules, if a named storm travels from one body of water, across land, and then into another body of water, the storm is renamed. It doesn't matter if the storm maintains itself or not, so in this instance, the origins of Arthur are irrelevant in its naming.
This is actually a very common misunderstanding.
A couple of years ago the policy was changed. If and when a system crosses into another basin, even by way of land, as long as its core remains intact and is very much the nucleus for renewed development, then it retains the same name.
This was not the case this time, however. As an example of what happened today, this situation is not at all dissimilar to TD 10 being dropped and replaced with TD12 (Katrina ATL 2005).
The core surface circulation of Alma did in fact wash out over the mountains of Central America, while much of its moisture and related mid-level vorticity went on to merge with a preexisting surface low which was birthed by the same parent broad area of low pressure. Additionally, it is likely that at least one approaching easterly wave interacted with this soup in a fashion that helped to get the new spins going, which finally took shape in what is now (officially) Tropical Storm Arthur.
Consider this from NHC's Special Discussion Number 1
