I suspect Jun (& possibly you?) are confusing the layer tag with
the level tag.<br>
<br>

<br>
I'm not saying Jun's edits are correct, but the layer tag has no
relevance to real world levels.<br>
The tag only refers to other entities overlapping similar space in
plan.<br>
It was created purely to help renderers determine which item to
display on top or underneath.<br>
<br>
Adjacent entities at the same *level* can have /different/ *layer*
tags.<br>
<br>
Your fourth bullet looks legit as there's a pathway passing under
the building.<br>

I suspect that it's tagging for the renderer or to get past iD's
validation, so can probably all have the layer tag removed. At
least this edit seems to have been made using Bing, not dodgy
sources.
