Three words for you ...
Sure, it doesn't help with altitude, although maybe a fourth word could be added for that, and "what floor are you on?" is a simple question to ask and understand the answer to anyways.
If people can be dispatched to a location, getting the altitude a few minutes later is still a good use of time. Not to mention, if you're in a tall building you've also probably got extra coworkers or neighbors to go to the elevator or go to the ground floor to help the responders get to the victim quickly.
Also, phones could be configured to automatically and quickly read the 3 words as soon as they connect to 911 so if they're calling a 911 call center that has not adopted any location technology the information can still be transmitted quickly, accurately and automatically in under 2 seconds to any phone without proprietary software on the receiving end.
