Yes. Note to self: always check accuracy before copying.

Yes. Typo.

Hmmm...very strange. I added these houses about a year ago, and don't remember any reason for that. You're right, not a normal tag, and doesn't make any sense. My guess is that (and the minor typo in the street name) are both cut-and-paste errors of some sort. I will delete the weird tag. Glad someone caught it.
