In fact, an if statement in Ruby is nothing more than shell-style 
booleans:

  if condition then main_stuff else other_stuff end

  condition and main_stuff or other_stuff

  condition && main_stuff || other_stuff

All of these do the same thing; they just they have different 
precedence.

Yes, any operator at the end of a line causes Ruby to treat the next 
line as part of the overall statement.  They're like an implicit \ at 
the end of a line.
