In a word, yes.

This is an SPI interface that has a master (the programmer) and a 
slave (the device being programmed).  The acronym MISO means Master In 
Slave Out while MISO means Master In Slave Out.  That's why you 
connect like-named signal lines together.  The clock line, SCK, is 
output by the master and input by the slave.  Likewise for Reset.
