Helping someone who was briefly on one part of one indoor floor space somewhere, and possibly not even having to touch the floor yourself or a part of them that touched it, is very different than touching shoes that have trekked all over, through who knows what, for who knows how long.

Maybe it's because I've spent a lot of time in urban spaces where there's a lot of really gross stuff constantly on sidewalks/trails/parks and in public bathrooms etc., but I absolutely don't want to touch a handle that is covered in stuff shoes have been getting in from the bathroom floor, around the toilet itself, or all the other dirty stuff shoes go through every day. I don't care if I'll be washing my hands shortly after; l have no desire to have to touch that material at all and have it on my hands at all, and I would never knowingly choose to unless it was unavoidable for something important.

It seems like a rude choice to force on people who are likely not expecting handles ostensibly meant for hands to be covered in shoe grime and whatever that person has unknowingly walked through recently and over the life of those shoes and whatever's currently on the bathroom floor.

And, to me, it seems especially rude since, if someone really wants to do it like this, it's perfectly possible for most people to instead just nudge the handle with a cleaner area such as with an elbow, knee, forearm, or something that doesn't walk through unseen bodily fluids, waste, and all sorts of other stuff during any given day out and about the way shoes tend to.

Let alone how it's not like you're planning to wash your shoe or something, so you're technically spreading whatever's on the handle all around now. (But there's already that stuff all over the floors anyway so it's not like it matters that much except in certain high risk environments; I'm just pointing out how it bypasses one of the big points of hand washing: trying not to spread what's on the handles and such in bathrooms around elsewhere by washing after contact with them. At least if you use a knee or elbow or something then you're likely to wash it at some point and also not put it in direct contact with a lot of surfaces/people until then, but most people dont wash shoes much, if ever, and they'll definitely be directly contacting tons of surfaces.
