This smell occurs when a worksheet overly related to another worksheet. This is possibly unhealthy for several reasons. First, adapting one sheet likely requires inspecting the other worksheet, requiring the spreadsheet user to switch back and forth between the two worksheets, increasing the chance that errors are made. Secondly, since there is a strong semantic connection between the two worksheets, the fact that they are split could influence understandability.
