Warning with adjacent government offices and corporate offices

[LeTopographeFou]

What steps will reproduce the problem?

1. Load Node 6129288820 and all features it belongs to (ways, relations...)
2. See that this node is at the corner between one government office (office=government) and one company office (office=company)
3. See that those offices shared a common part of their outlines (but that there are no intersection or overlap)
4. Launch 'Validate' in the validation panel

What is the expected result?

There should be no error (at least not the one described in this issue)

What happens instead?

There is an error stating that those offices overlapped

Please provide any additional information below. Attach a screenshot if possible.

I think this is a false positive and that it is totally ok to have such situation.
