I often see this mistake done in the staging of a CAT tourniquet. In this video we talk about the importance of having the Combat Application Tourniquet (CAT) staged correctly for life safety. 
I also put a little fold at the running end of the material, acts as a good grab point and will not allow the end to slip thru the buckle. I also fully extend to make a big loop, then fold it all back up 2 or 3 times, It will go over the biggest boot. I have to pack them in a bigger t-holder because I could never get them back into the plastic belt holder. I keep 3 or 4 in the truck, one is in the door cup holder with no bag or case, just there ready to go. Got to replace that one, been there a little while.
