I am inclined to believe that the first reporter only thinks they saw this, not that it actually occurred (or they saw some random words appear on the keyboard that resembled this phrase).
Anyone who worked with users would tell you stories about the stories the users tell to support about how they "didn't do anything at all, didn't touch it and now everything is gone! it's your fault!"
By the way, yesterday my Apple Watch 2 popped up a keyboard and wrote "pflenker is leichtgläubigertyp!" can you believe it?!
