Guys, If a guy opens the door for a female like a door man and then presses the button in a elevator for her, does it mean his attracted to her?

So today, a guy I've seen around campus but never interacted with was quite chivalrous towards me. We approached the entrance door way of college around the same time and then he went in first but opened the door like a door man from the inside instead of just holding it open from behind with his hand. We then got into the elevator together and as soon as we did, before I could even press the button for my floor, he was like "what floor?" and then he pressed the button for me. What's strange but sweet about all of this is that there was no one around, just the two of us, so I was perfectly capable of pressing the button myself yet he chose to take initiative for some reason.
