Ok, this is my unlearned take on what is being said.
We cannot get glycerin through diet; it must be synthesized from glucose. The glycerin is then used to form triacylglycerols for fatty acid storage in the adipose tissue. When the body needs to use the stored fat for energy, the triacylglocerol is broken down, releasing the glycerol which can be used for glucose synthesis. So, you can get glucose from stored fat, but it is not enough to restore (or even maintain) the glycogen in the muscles.
