I think it is more because premier league football has evolved to a more offensive approach the past few years.
When you have coaches like Guardiola, Pochettino, Klopp coming in to the premier league, it seems like they brought new ideas and concept that was very different from the Mourinho, Ferguson and Benitez era.
Now it's all about creating chances with pressure and players high up the pitch. Forcing errors, having higher possession %, and suffocate the other teams. Therefore top teams goalkeepers are not having as many shots as in the past but more quality shots. Also they need to be good with their feet to create counter attack and build up plays.
That's also IMO of the biggest reason behind the sudden rise of English Football in Europe (Champion League and Europa League) and why the current Liverpool/Manchester City team are to be considered some of the best premier league teams of all time.
