UART1 dual identical pins in K64

In K64 I've noticed there are multiple pins (all are ALT3 as well) for the UART1 interface: pins 1,2 & 73,76 for RX,TX.

Is there any difference between them? or how should I use them?

I've tried using UART1 on the FRDM K64 (K64 pins 73, 76 for RX, TX) and it doesn't work, trying to understand why...

Kerry Zhou/ Mark Butcher - do you know?

Thanks.
