SearchInColumn "hits" in multiple columns, highlighting doesn't always happen

[poetaman]

I tried :SearchInColumn for csv in my last bug, it has false hit for a cell that is not in column passed to the command. In the screenshots below, SearchInColumn 1 /Alex/ should not have hi-lighted Sir and Alex on line number 5. Also, the highlight doesn't really happen when :SearchInColumn 1 /Alex/<CR> is entered the first time; and only starts highlighting entering :SearchInColumn 2 /Alex/<CR>n

The same problem does not occur when search is repeated in column-2:
