Huh? Did you actually read what you posted? The article you cited argues that the strain is different and only distantly related to strains in the Congo.
I did.
I cut/pasted the wrong link.
This one is better:
“This approach indicates that the outbreak in Guinea is likely caused by a Zaire ebolavirus lineage that has spread from Central Africa into Guinea and West Africa in recent decades, and does not represent the emergence of a divergent and endemic virus.”
There’s actually quite a bit of contention as to the classification of the strain of ongoing ebola. But the sequence analysis presented in this paper indicate it’s still closest to Zaire strain and likely doesn’t represent an entirely different on (bun, sudan, tai forest, reston)
