Yes, but the size requirements for that partition have increased with newer releases, even within Windows 10 releases. So if you try to upgrade to a new version of Windows that requires more capacity on the Recovery partition than your current Recovery partition has, it has to address that. Since the original Recovery partition by default is the first partition on disk, it isn’t possible to extend that one in place. That’s why the Windows upgrade process instead shrinks your OS partition by some amount and creates a new one in that freed up space. After you have a Recovery partition immediately after your OS partition, any future needs can be met by just incrementally shrinking your OS partition by the additional amount necessary to create more space for the Recovery partition.

Of course it would arguably make more sense for new Windows installations to just create the Recovery partition after the OS partition in the first place so that you don’t end up with a “dead weight” Recovery partition at the beginning of your disk later. That incidentally is exactly what the TechNet deployment guide now recommends, but for some reason Windows Setup as of this writing still places the Recovery partition first on brand new installations. One possible reason is that when your OS partition is the last one on disk, it’s a lot easier to clone to a larger disk and extend that partition to fill the new space. If you have a Recovery partition after your OS partition, you can’t do that after the fact; you’d have to stage the clone differently upfront.
