I don't really think so.
Ratings and reception usually dictate the success and longevity of a series in Philippines, and the main reason why it keeps on going is because shows are not canned. Perhaps, there could be a rise of 'shorter series' because of covid, which leads to shows being canned.
He's into her is produced by a network that is no longer in broadcast. And I presume that the network has a more flexibility and becoming more experimental since they had to think of ways to attract viewers either via its cable or streaming route. GMA, which is a broadcast network still continues to produce shows that are longer (and on-going filming). I believe Voltes V is probably a much shorter series because they are going to film and post-edit the whole thing before it gets aired.
The norm still up to this date in Philippines is people watch soap operas from Monday to Friday, about 20-30 minutes per episode, and usually run about 2-3 months. More popular series would run an additional season or get extended by then, which is why you would see shows having at least 60 episodes and goes beyond 100 episodes (for popular ones). You have to think that network needs to fill their schedule with programs and it will be more economical for them to promote (ads, etc) a longer series rather than a shorter ones. In the case of He's Into Her is a different story, it's in a streaming platform so it does not have programming timeslots to fill in. And even in the case of ABSCBN (now in its cable network), they are still producing soap operas that are "lengthy".
So, generally speaking I doubt this will be the norm, but more of an exemption and could be 'special shows' and probably treated like a mini-series or long movie (much like some shows of this network where they air episodes on Saturday for 1 hour over a month or two - which is about 8 hours/8 episodes).
