No worries, you didn't mess anything up and it wasn't wrong just incomplete, and I was giving you a few tips to make it better next time. If there really was something wrong, I would have gone ahead and fixed it right away :) Thanks for explaining the situation more in your other changeset comment, and sorry if I wasn't as kind and understanding as I should have been!

It took me a while to fully figure out crossing tags and get them 100% right, though nowadays the PWG has a schema and guide that has all the details in one place: https://wiki.openstreetmap.org/wiki/Foundation/Local_Chapters/United_States/Pedestrian_Working_Group/Guide As a new PWG member I am gonna work on making it friendlier and more accessible for new users.
