No, Flexi-binding isn't Layer binding. Flexi-binding, by default, makes all the layers affected by all the bones. You can adjust how strongly the bones affect different parts of the body but the result can still look kinda 'squishy'.
This is where Use Selected Bones For Flexi-binding comes in. This method lets you exclude the influence of unselected bones from selected layers, eliminating that squishiness described above.
Layer Binding (using the Bind Layers tool,) binds the selected layer(s) to a specific bone. It rigidly 'parents' the selected artwork to the bone you click on, and no other bone will affect that art. For example, if your character carries a sword or a club, you might use Layer Binding to bind that item to the hand bone so it doesn't get deformed by the rest of the rig. Note that you can still animate the points in the bound layer with point animation, just not with other bones.
If you wish, you can use Layer binding to bind fully segmented character art. This would result in a true 'cut out' style puppet, kind of Monty Python style. But if you want the layers to deform and bend smoothly, and maybe suggest a more 'FBF'-ish look, then you're better off using Flexi-binding.
Either approach is a valid technique and can look good when it's done well. They're just different animation styles.
