It is not exactly incorrect, but it is very ambiguous.

The expressions referred to all START with those those three terms, but 
they finish at different places...

34140: Expansion of (1+x)(1+x^2)...(1+x^10)
34141: Expansion of (1+x)(1+x^2)...(1+x^10)(1+x^11)
34142: Expansion of (1+x)(1+x^2)...(1+x^10)(1+x^11)(1+x^12)

and so on..
