Question: same command, different output form

i've come across a confusing behavior where the same command (a copy/paste of another command) is giving an output in a a different form.

Attaching a screen shot that shows this. Eq 6.8 is executed just after 6.7.

(i know the command is weird, i.e. subs(beta=beta, ..), etc.. this is part of some larger code base and i just put this in when trying to undertand what's going on).

I would hope for the same command to spit out the same output in this case. (nothing else gets assigned/called in betwen).

any idea what's going on?

 

i'm on maple 2018.2 on linux.

thanks
