Icon "xxx@yyy.com is viewing" a note in an expected Private notebook

[rdp2014 0]

There is person A and Person B. Person A has access to the following:
notebook 1 -> private
notebook 2 -> shared: person A is owner: Person B can edit and view
notebook 3 -> shared: person B is owner: Person A can edit and view
But, person A when editing a note of his in notebook 1, could see the light blue icon along with the tooltip "person B is viewing" when the mouse is over it. I marked it in the red circle in the image below.
Any ideas why that might be? Thanks in advance.
