Since the whole thing is not documented anywhere, it's hard to rely on or exploit. From my experience, it works.
Check out search results on "gsuite legacy storage increase 5gb", multiple users reported on their experience with it. It looks like extra space is granted if you're close to the limit, but not over it, for ~1 week.
There are also single reports on Google taking back the extra storage - back to 15(17)Gb - for people with extreme (ab)use of the feature, who stacked hundreds of gigabytes through 5Gb steps. Couldn't verify any of them.
I'm using 50-license GSuite since 2009, if that matters.
