I have been here:

https://na.finalfantasyxiv.com/lodes.../housing_land/

where you can see this:



But only the first part of the highlighted sentence is enforced, cause you can do this:
1)You own a private and a Guild house where you are GM.
2)You make another character that join a guild with a house (maybe bought by a friend or a second account).
3)Your friend makes your second character GM of that guild.
4)You can MAiNTAIN both Guild houses
4b)In practice you can redo 2-4 more times, till max of 8 guild houses for account (edit: per world).

can someone pls confirm this is working as intended? cause for me the MAINTAIN word is key to the issue. English may not be my mother language but i understand that what is wrote IS NOT what it is happening.
