Why two tags starting with <script> on same page?

[webmanz 1]

Re LESSON 1: Event Handlers - part 1

You have two sets of <script> on the same document, is there a reason for that or is it an error or are you allowed to do that?

at 3 min mark (bottom of document) and then compare to 3.25 min (top of document)

 

Update: problem solved.  In lesson 6 there was additional code not visible in lesson 1
