it's not an unusual callout for an Amazon job. Some roles are very technical, you can be heads down working on code or doing data analysis almost all the time and what talking you do is to your teammates. If you need to communicate up in your own org you just tell your direct boss, across orgs you tell a program manager, either of who will be reasonably technical. Other jobs you are expected to present directly to the higher level, non-technical folks. L7 is "upper middle management", so likely have been in the management world for long enough to need some abstraction laid onto the detail.
