Well, look at the quoted info last two sentences, that's the meaning of a disclaimer...

disclaimer = include statements to the effect that the publisher (you) will not be held liable for any unforeseen circumstances that might arise as a consequence of using the software. This could refer to anything from a computer crash to loss of data, time or income.

edit: in effect similar to the limited liability, but you specifically disclaim any responsibility for any loss of data, time or income...

cheers,
