Ok, looks like I got receipt of how to reproduce this bug:

1. create new file.
2. write some stuff in first cell and press Shift+Enter to execute and create new cell.
3. write some stuff in second cell and press Shift+Enter again.
4. select first cell with mouse make some changes and execute again with Shift+Enter.
5. While second cell marked blue, press Cmd+Z
6. Select first cell and press Shift+Enter.

You will see execution results from previous state, not from current.

Here is a video demonstations and logs:
