RSI compares the size of recent gains with recent losses, so a reading above 70 says buying has dominated the last 14 bars — not that price is high. A long stay above 70 is a market trending up, which is the opposite of the reversal the word 'overbought' suggests.
Here the reading entered overbought territory 10 times, with a median stay of 35 minutes and a longest of 220. A brief excursion above 70 that resolves in minutes is noise on this timeframe. A sustained one is the signature of a trend that is still running, and selling into it is how traders get run over.
