Yes, as far as coil current it makes no difference.
The difference is in polarity of the spark. If coil is connected to match battery ground the plug will "spit" the spark from center electrode to ground tab. If coil is connected opposite of battery ground the plug will "suck" the spark from grounded electrode to center. The plug is more efficient when it "spits" the spark.
I have seen several instances where tractor's first start up in the morning, even in summer time, was much quicker with coil connected to match battery ground.
