xenoRefGene description says: This track shows known protein-coding genes from organisms other than [your organism], taken from the NCBI mRNA reference sequences collection (RefSeq).

Whereas refGene contains only genes from [your organism].

You can find this by clicking the "Describe Table Schema" button on the UCSC tables page.

There is more information about refSeq here.
