I’m not really a fan of them in general; I’m not sure what they do functionally especially on a knife with a guard. I’ve heard them described as for the user to “choke up” on the blade.
No, I am pretty sure that that "Ricasso" or "choil" on a Bowie is primarely for what I described above already: If you stab something and the blade gets stuck in the material, one can put one finger in that "choil" and push back against the front side of the guard, while pulling out the blade. The pulling out is made easier by that.
