Basic question about splitting gas line

I just picked up a gently used single tap kegerator. I have it running lines for a single keg but I’d like to split the gas line so I have a second available to flush equipment and carbonate a second keg so I don’t have to disconnect the beer on tap. I purchased an air distributor to split the line.

Question: When I add the distributor should I cut the existing gas line and put the distributor in the middle so the existing line remains the same length or is there a reason to add more line before the distributor and keep the existing line the same length?

Gas line length is inconsequential. Make the length long enough to be useful and short enough to not be in the way.

Yep
