When you build up to the build limit, and try to place another block, it will tell you "The height limit for building is 256 blocks". When you go to y=0, and place another block below, it will tell you "The minimum height for building is 0 blocks". This is as intended, however the minimum height message is given to you 7 times when you only click once.
