Yeah that is normal. Generally, wire tying causes the skirt to be held up against the shaft of the hook much tighter than a rubber collar which has more give to it which is why you see the fanning of the skirt material. I like to use more material above the wire tie towards the eye of the hook so that when I tie the skirt and lay it back as it would be fished I have a skirt that is even/almost even with the skirt at the bend of the hook behind the tie if that makes sense.
