The matched loss in parallel runs of coax, whether wired in series (to 
double the Zo) or in parallel (to divide Zo by two), is the same as for 
a single run of the same coax.

The virtues of parallel runs are the lack of interference with 
surrounding objects and the impedance transformation of the series or 
parallel connection.
