This is fairly easy as long as you don't mind empty entries in your 
resulting list.  In C1 enter:
=IF(ISNA(VLOOKUP(B1;A$1:B$5;1;0));B1;"")
and fill it down the column.

This will display in column C your required Jason and Steven, but in 
their original places as in column B, with empty cells where names 
were matched.  But it will update as you modify column A.  If you 
were fussed about the empty cells, you could sort the values, but you 
would have to copy the values in C somewhere else first, using Paste 
Special to freeze the result values, and then sort those values 
instead.  The sort would otherwise have no effect on the formulae in column C.

I trust this helps.
