question of chemical notation

[gib65]

Please have a look at this diagram of 5-meo-dmt:

 

 

Is there any reason why the terminal molecule on the upper right branch says H3C whereas the other molecules on the other branches say CH3? Does it matter in notation whether the H3 comes before or after the C?

[Penny]

They are the same. It's just a different way to represent a methyl (-CH3) group.

I've seen such things as well. Is it the idea that the two terminal carbons look like they're part of a benzene ring? In nature, would the two hydrogen groups tend to "repel" each other? I suppose one could ask why the two carbons are split so wide apart (Again, "remnants" of another ring?).
