Sorry I used the term "fpa" in a wrong way in my previous post.
The given frames are the length of the whole animation for a swing.
In this case, "12 frames" (non glitch) means you deliver 2 hits (one with right and one with left weapon) within 12 frames. That's 6 fpa (frames per attack).
10 frames (glitch) is 5 fpa.
There's no difference for the total length of your swing between 46ias and 63ias (un-glitched). Both are as fast in the long term.
There could be a difference on the action frame however (you could hit sooner in the animation).

e: and does the glitch thing work like i put death on left weapon slot and grief on right and click grief twice and then it gets glitched?
If "left weapon" refers to boots-side, I don't think you would be glitched, because gloves-side weapon is already your main weapon (default setting).
If it refers to gloves-side, yes, that's how it's working.
