No, that's a bad trick to rely on for speed these days. GNU grep's speed comes from using memchr in its skip loop. Skipping bytes is only going to matter when the thing you're searching for is longer. For short needles, there isn't much opportunity for skipping, so it's better to say inside a vectorized routine like memchr (which, for glibc, is written in Assembly on most platforms).
