In general, it could be either really.
I think especially if you met OD, there IS a lot of pressure on both sides to "make your mind up".
I agree things like sexual exclusivity are important to be open about (if only for the health aspect) and also if you're on a tight schedule exclusivity is good to discuss.
but dating is about both of you just spending time together and seeing how things go?
It shouldn't be gendered, with a woman wanting the guy who will "choose" her straight away and a relationship for the sake of being in one.
The culture of dating can be fun, but also it puts pressure on both parties : some of the best couples I know met through just spending a lot of time together platonically and evolving naturally.
That said, I think THIS guy is a timewaster and will be an energy drain.
The fact that he's felt the need to tell you what he thinks you think (as opposed to actually having a conversation) and cancelled rather than have a proper appropriate discussion implies that
(1) he lacks social skills and is a bit passive-aggressive
(2) he's one of those guys who likes to fantasise that all women are the same (rather than individuals) and because they have a vagina are Bridget Jones and trying to get him up the aisle next month.
(3) like others have said, he's maybe thinking he wants to keep his options open
