Hello and welcome to OpenStreetMap!

I'm not sure what adjustment was made here - it seems to be a small adjustment to building geometry.  One thing that it might be useful to know is that if the underlying building is rectangular (as appears to be the case here) then you can "square up" buildings in OSM by pressing "q".  Also, I notice that diffrent imagery sources here differ about the "imagery offset" here.  I don't know which is more correct, but there are lots of mappers in the Philippines, and asking at https://community.openstreetmap.org/tag/philippines would probably get an answer.

I also don't understand the comment '[I just adjust “areas” to avoid copyright infringement.]' on your profile :)

Best Regards,

Andy
