Guy I’m dating updated his tinder profile?

I’ve went on 3 dates with this guy we’ve been talking for about a month and they all went really well and we text all the time. At the end of the third date we ended up having sex and we’ve been talking as usual after and talking about meeting up again, only I just noticed he added two new pictures to his tinder account. Why would he do this? Should I say it to him or just leave it since we’re not official.
