Let's imagine what happens if you use your contaminated tip from the last dilution:
You wouldn't only transfer cells from the diluted solution, but also take some cells that stick on the tip to your next dilution. So in effect, you will have more cells in the new dilution than you would expect - and your experiments results are improper.
