It's what they told me. Based on other conversations with them about other powders they mfg. I've got no reason to believe it's not true.

It's common knowledge that the exact same powder is sometimes sold with different labels. As an example it's commonly known that H414 and W760, and W297 and H110 are the exact same powders.
Remember the GFY can go in both directions.
