That’s the best version. People leave with washed hands so hands remain clean and it’s possible to enter by pushing with a foot.
The other way requires using the door handle while entering. That can contaminate the hand that is going to touch or get close to the private parts. It’s better to have that hand as clean as possible.
Clean, dry and uncut hands create a formidable barrier to pathogen transmission. And the most dangerous pathogens tend not to live long outside a living body.

So better not wash hands, especially if one had to touch a dirty door?
No. My point was that dry, unopened human skin makes pathogen transmission by touch nothing to worry about.
