Start with … 2 words

Hi, is need to use the start_with with 2 words but not works.

For example :
My titles are :
1) “first second”
2) “first seconds”
3) “first second2”
4) “first third”

I wants to show all except 4)
Is possible ?

starting_with – Get posts whose title starts with a certain
letter. Example: [catlist starting_with=”l”] will list all posts
whose title starts with L. You can use several letters: [catlist starting_with=”m,o,t”].
