This person is so holy that they drink water.
The very fact that it was a sign of unusual holiness to drink water seems to undermine the point. It's like saying "in the 2020s people mostly didn't use cell phones. Look at this passage about a group called the Amish, see what I mean?".
By the way, this is the mainstream position among historians, it is only pop culture that hung up on the water myth.
