"It was known that green tea polyphenols are more effective and offer more health benefits than black tea polyphenols since green tea chemicals are absorbed into the blood and tissue," said Susanne Henning, the study's lead author and an adjunct professor at the UCLA Center for Human Nutrition. "Our new findings suggest that black tea, through a specific mechanism through the gut microbiome, may also contribute to good health and weight loss in humans."
That specific mechanism seems to be that it changes the ratio of bacteria in the intestine by increasing the microbes associated with lean body mass and decreasing those associated with obesity. While both green and black teas act as prebiotics in this way, it seems that black tea might have a leg up over its green partner.
The study fed four groups of mice different diets. One group ate low-fat, high-sugar foods,while another had high-fat, high-sugar meals. The other two were both on a high-fat, high-sugar diet but one got green tea extract, while the other received black tea extract.
[...] Because black tea seems to work in the gut, while green tea works in the liver as well as the gut, a combination of both drinks might be most helpful, especially since both beverages have been linked to multiple health benefits beyond weight loss.
The researchers did not specify how much sugar to mix with your black tea.

What is the significance of the leaves being decaffeinated?

Presumably the stimulant effects of weight loss from caffeine.
Often the unsaid is the most interesting part of the story, perhaps they can't use regular because they're using like 500 grams per kilo of mouse and the caffeine dose would kill the mouse. Thats how I'd interpret it without reading.

The black tea is not decaffeinated. The article linked to in TFA mentions decaffeinated green tea and black tea (not decaffinated green and black teas). TFA doesn't mention decaffeinated at all.
The headline of TFS is incorrect.

The "decaffinated" in the headline of TFS appears to come directly from the headline of the study, not the linked TFA.
No, you are mistaken. I've always had this sig.

Caffeine - being a powerful stimulant - would be suspected of skewing the study results.
