Some clarification:

Yes, macros are fed into C code to run. The C code splits it into lines that are then fired back into the Lua environment using the EXECUTE_CHAT_LINE event. (See ChatFrame.lua)

The lines going through all the /cast commands actually do get run, but the block is in CastSpellByName()'s C code, not the macro "parser".
