Does the length of the cheek kiss a guy gives you matter for the meaning?

So, of course there‘s a background for this question but I‘d ALSO like to know it generally speaking.

in a nutshell I saw my crush (nothing happened between us yet but the spark is DEFINITELY there, like, even friends notice it) yesterday at an event. He left earlier with another girl but told me he‘s staying at her apartment for the weekend because he has a lot of meetings and events in city center and driving would be stressful and inpractical. Mind you, he‘s driving 30mins between his own home and city center. And before you say anything: this is completely believable but I don‘t want to stress you with the details. Just trust me on that. Now, when he said that alongside saying goodbye to me he kissed me on the cheek but it was a 2-3 seconds kiss with lips presses very firmly to my cheek. It almost felt like he wanted to assure me that there was nothing suspicious going on with that girl and but in a sweet, positive way and that he‘d rather leave the event with me? Bit maybe that‘s just my interpretation so feel free to ignore that.

Now, is there a difference when a guy kisses you on a cheek? Like, say a quick peck and then a good 2-3 seconds pressing his lips on my cheek?
