I see how that sentence is ambigious. I meant that you have it correct. The two key elements being "short term memory" and "items (variously defined)".
This article thinks it applies to long term memory, and most people don't realise you can 'hack' this by chunking 'items' into bigger 'items' (e.g 7 two digit numbers have 14 digits total).
