Memory bug in Advertising Conditional

Possible bug in Advertising Conditional?

I entered a very simple answer, single if-else with nothing but a println in each branch.

Message on run is

Your code passed all the tests! Props!

But we noticed something you could improve:
  Your submission uses too much memory:
    The solution allocated 488 bytes to complete the tests.
    Your submission needed 13016 (2667%).

Rewriting into a single println with a ternary operator inside to choose the print string doesn’t produce this message, but fails because ternary conditionals are outside the style conditions.

Same memory message on Chrome(Linux), Chrome(Windows) and Firefox(Linux).
