Why split the <script> tag when writing it with document.write()?

I have frequently seen the following statement:

document.write("<scr");
document.write("ipt language=\"Javascript\" type=\"text/javascript\" src=\"source url\"></scr");
document.write("ipt>");

What is the advantage of this? Why don't people write the whole script, as below?

document.write("<script ");

Depending on the browser, the amount of other preceding javascript, and how well-formed the overall code is, this is done to prevent the parser from interpreting the and tags as executeable code rather than as a string to be written.

I have found that it just saves headaches down the road if you do this when using script to write script tags.
