The Church does not deny that those with homosexual tendencies cannot be chaste

Why can't they??

I suspect that the double negative is unintentional.

"Why can't they??"

I also think the double negative was just sloppy writing, but they blundered into the truth quite by accident.

SSAD is defined by a pathological compulsion to be unchaste. The thing about pathological compulsions is that they are too strong, and the individual too disordered, to allow any confidence that the disordered person will not falter.

It's hard enough for a healthy man to resist normal desires. To expect a disordered person to resist pathological compulsions is just silly.
