When Selenium IDE converts html into php, why doesn't it create simple Selenese commands?

I am using:

• Selenium IDE version: 1.0.10
• PHPUnit 3.4.15

If I use Selenium IDE (the firefox plugin) to create a very simple test case, with one command in a Selenese table row:

waitForElementPresent | css=div

Then use the Selenium IDE > Options > Format > PHP feature to convert that code into PHP.

I get something like:

<?php    
...    
class Example extends PHPUnit_Extensions_SeleniumTestCase
{
  ...
        for ($second = 0; ; $second++) {
                if ($second >= 60) $this->fail("timeout");
                try {
                        if ($this->isElementPresent("css=div")开发者_如何学运维) break;
                } catch (Exception $e) {}
                sleep(1);
 ...
}

My question is:

Why is that PHP code generated in such a convoluted way?

I could convert that command into something like:

<?php    
...    
class Example extends PHPUnit_Extensions_SeleniumTestCase
{
  ...
        $this->waitForElementPresent("css=div");
 ...
}  

The latter line of php would make use of the magic method in the parent class: PHPUnit_Extensions_SeleniumTestCase::__call($command, $arguments)

What is the reasoning behind this kind of convoluted PHP output?

• Is it just to make the PHP less reliant on PHPUnit?
• Is it because it is a patch on a bug?
• Is it because it gives better test result feedback?

I'm asking because I am a selenium newbie and am wondering whether there is any reason why I should not just write my methods in the selenese-style of that second code example (above).

All those are written because of bugs that will occur in:

$this->waitForElementPresent("css=div");

For instance selenium's code have a timeout among lot of other things...
