what does it explains ?

accurate base pairing is req only in 1st 2 nucleotides of mRNA codon, so codons differing in the 3rd wobble position may code for the same tRNA /AA.
it's like a SILENT mutation

and it explains that genetic code is degenerate

Isn't the wobble hypotheses that the third position of the codon on the mRNA and the first position of the anticodon on the tRNA are bound less tightly(hence the wobble) than the other 2 base pairs, allowing a single tRNA to translate several different codons for the same amino acid?
It accounts for the degeneracy of the genetic code and also allows unusual base pairing to occur.
