My question involves criminal law for the state of: Pennsylvania

I was in a bit of trouble the other weekend. Basically, this guy was mouthing off and I ended up punching him in the face. The cop told me I was going to get two citations issued to me (one for disorderly conduct and one for harassment). My friend also was told she would receive a disorderly conduct as well and we live together. We got two envelopes yesterday, and in each were disorderly conduct citequalingualling the same price. Hers stated she got it because she was yelling and was disturbing the peace/society. Mine said it was because I hit the guy in the face. I'm wondering if you're dealing with one situation at hand and there are multiple citations are they normally sent together? And if there were going to be two wouldn't that harassment be because I hit him in the face? I am wondering why they didn't come as one big fine. I know that the cop liked me, and told me it sounded like the guy deserved it so maybe he's letting me off with just the disorderly? I am really confused and wondering if citations are normally mailed together or separate? And if they are separate wouldn't I have gotten it the same day? Please let me know anything you can or even just your opnions. Thank you!
