I think the answers to your questions can be found in the news you cited dallasnews.com/sharedcontent/dws/news/texassouthwest/stories/DN-monastery_07tex.ART.State.Edition1.3e8b0d6.html:
That association (with ROCOR) ended eight years later following the allegations of child sexual abuse, as did the monastery’s practice of accepting novitiates under age 18 – and as young as 12. The cadre of full-time monks dropped to about seven.
“That year, we received evidence from a mother of a child at the monastery that sexual misconduct had been occurring there,” said Nicolas Ohotin, spokesman for the Russian Orthodox Church Outside Russia. “Within 24 hours, the church suspended the clerics and dissolved our relationship.”
Previously, the church had sent priests to Texas to investigate concerns raised about activities at Christ of the Hills, but they never found sufficient evidence of wrongdoing, Mr. Ohotin said.
So, from being canonical they became non-canonical and seems to have continued operating on their own.
