I'm not quite sure what this is supposed to demonstrate. In the cases where you have specified the tab character correctly ($'\t'), it's converted into a tab before matching is attempted. You can tell this because in the cases where you have not, either the literal `$' gets removed, or the literal instances of \t in the value of parameter are removed. Since there are no tab characters in $parameter, no tabs get removed when you specify $'\t' correctly.
