How's it sound in lame 3.100a2?
(I'd also be curious what the -Y switch does with it, but I suspect that'd be straying off-topic.)

You tell us.
-Y is not a low-pass. If you want to create an output of two tones you will likely need to use a low-pass. I doubt -Y would do much of anything as this sample likely isn't complex enough to starve the encoder of precision in order to meet the quality threshold of -V0, even with the ill-advised, overly-tight corner.
Remember, samples beyond FS are a decoding artifact, not an encoding artifact.
I'll admit that I didn't hear a difference at all. But I have far from discerning ears - I cannot hear anything in the top band (15.7kHz or higher), and frequently cannot ABx what others can.
I typically use -Y instead of a lowpass filter; I'd rather preserve some semblance of the top band, even if I cannot hear it, in case friends or family listen in. It didn't sound, or look, like -Y did much in this case...probably because, as you said, it was such a simple sample, and the upper frequencies weren't causing bitrate bloat.
