seems like you have to put parentheses around the second 'test',
as 

true && puts('test') #-> test nil

as expected. So this is a priority thing.

but now I am puzzled about the following:

irb(main):021:0> puts(1 || puts(2))
1
nil   #-> fine with me

irb(main):022:0> puts(1 or puts(2))
SyntaxError: compile error
(irb):22: parse error
puts(1 or puts(2))
         ^
 (irb):22: parse error
 	from (irb):22

what's the problem with using "or" within parentheses?

irb(main):029:0> puts(1 or 2)
SyntaxError: compile error
(irb):29: parse error
puts(1 or 2)
         ^
 	from (irb):29
