What are “suitable” revisions?

r/

I apologize for being somewhat clueless. My first manuscript received a major revisions decision several months ago. I re-submitted in March and just got reviewer comments back again, with an invitation to make “suitable revisions” this time around and resubmit. I’m wondering how this differs from a major revisions process, or if it’s essentially the same? Is this a common phrase to use?

Thanks!
