Default Picture boundary in HEVC/H265

Hi,
As per some papers on hevc standard:
"the boundaries of the picture are defined in units of the minimum allowed luma CB size. As a result, at the right and bottom edges of the picture, some CTUs may cover regions that are partly outside the boundaries of the picture. This condition is detected by the decoder, and the CTU quadtree is implicitly split as necessary to reduce the CB size to the point where the entire CB will fit into the picture"

Can anyone please explain what exactly is the scenario here? I mean shouldn't the boundary be detected in terms of number of CTBs only?

Thanks in advance
