I'm not sure but there are some statements in the code like this.

Steemit will give you extra TRX reward, this tron account was used to receive those reward. System will automatically create a free TRON account for you. Do you agree creating TRON account and download a pdf file with TRON keys?"

My first impression is this may be an option to earn TRON in a similar way to the LEO or PAL sidechain tokens, but that is probably a best case scenario.
