front, front1, front2...

This question is regarding front and back as used in extract variables.

The documentation states that you can separate multiple variations using "|", so what's the point of having front1, front2 and so on? Wouldn't just "front" be enough? What's the difference between:

front = a|b

and 

front=a

front1=b

?

Also, what if front5 doesn't exist? Will front6 and the ones following still be taken into accout?

For ex. lets say u can meet 2 versions of that, one with " and one with '.
And we want to get url to your profile = /profile/ihulub

<a title="ihulub" href="/profile/ihulub" class="PhotoWrap">

<a title='ihulub' href='/profile/ihulub' class='PhotoWrap'>

[profileurl]
type=extract
front1=<a title="|<a title='
front 2=href="|href='
back="|'

What if you used this instead?

front=<a title="|<a title='|href="|href='

back="|'
