Texas, Louisiana both halted imminent executions on Tuesday. What’s going on?

In nearly simultaneous decisions, courts in two U.S. states on Tuesday blocked the imminent executions of Death Row inmates.
The highest court in Texas issued a stay of execution for David Leonard Wood, who has always denied being El Paso’s so-called Desert Killer and reiterated his innocence of six murders in a recent hourlong interview with USA TODAY.
Wood was set to die by lethal injection on Thursday, a little more than 48 hours after the Texas Court of Criminal Appeals stopped it.

Within minutes of the Texas decision, though it’s unclear which ruling technically came first, a Louisiana judge temporarily blocked what was to be the state’s first execution by nitrogen gas, finding that the largely untested method could cause the inmate, Jessie Hoffman, “pain and terror.”
Hoffman was set to be executed on March 18 for the rape and murder of 28-year-old Molly Elliot in 1996 in a crime he has partially acknowledged committing.
Stays of execution are relatively rare, but two back-to-back even more so. So how did it happen that way Tuesday?
