Well, the parent doesn't say that Yeager said bad things about Armstrong, just that Yeager was happy to spread falsehoods. I could easily see that being Yeager telling somebody "Oh yeah, did you hear that Armstrong benched 450 yesterday? It's a new personal record for him, make sure you congratulate him!" or something similar. Making up harmless lies as a practical joke, that sort of thing.
