Well I would imagine that you'd do it to force the Terran to play defensive, as opposed to having hellions run around the map giving map control. It also may delay the expansion. The purpose isn't to make him do some huge commitment to something stupid, it's to make him not be aggressive/play less greedy. Or at least that's how I'd view it. I'm not the OP though, so don't let me put words in his mouth.

It just would set _you_ behind, not the terran.
