I don't think this is wise mustache-management. I suppose he is trying to avoid the opposite extreme, which also creeps me out incidentally -- the mustache that looks like it is trying to crawl into the wearer's nose. Also not the best look.
I knew a kid in high school who grew a mustache once, and there was a large space in the center with no growth. Two furry strips, and a distinct space in-between. I always thought it looked a little bit like two caterpillars had crawled onto his lip and died there. To make it even more disturbing, his eyebrows matched the mustache-pieces almost exactly.
Gentlemen: if you choose to sport facial hair, you should think very carefully about what it looks like, and the repercussions!
