"Masterless technique? I'm not sure what that is, let me check," said Mateo as he paused for a moment to check the temple catalog. He was technically only a caretaker to ensure that the temple keeps operating normally until it activates fully, and all those in hibernation wake up. Thus, it was perfectly natural for him to not be aware of all the details of the temple.
Even with all the workers Lex had been sending to the temple, it kept operating in a hibernation state for it was built to deal with numbers far greater. The only thing that concerned Lex was whether he'd be able to learn the Masterless technique in the temple's current state. He almost entirely expected that there would be any number of things he'd need to do first to be able to learn the technique.
