The general issue is 
* lack of automatic tests on sample (data) files... So copy sample X to new
sheet etc
* Test framework on probably Linux machines.. so Windows specific bug are
invisible

There probably a good reason for the commit; with good intentions. However
improving case A, makes case B worse.. Or uncovers another bug.. 

However without now what the comment attempt to do (for what case in mind)..
it's only hard to tell. 


Note:
You did select the columns & used delete columns (there is no issue full column
content is selected and deleted)
