It will work the same still better to reel in at the van holding hose with a cloth,the side bars will stop it going over the side and knocking the chain off.
It’s not a problem when a small amount of hose goes over the side,the real trouble starts if 4/5 rotations go over if you’ve not dealt with that before it can become a bit of a nightmare,at that point you may have to cut the hose off that’s gone over untangle it cut off the fitting and replace it on another section of the hose.
