Since you're speaking plain english here the questions you're asking could come from anywhere. And have a home in any context. And mean any thing. So in general it is hard to comment on your questions.

However, I know that "I putt as I drive" comes from Boomer. And I really like that one. The putting being a scaled down version of the driver stroke, with power accumulators zeroed. There are a few common assets between full stroke and putting as far as pressure point alignment, low point, aiming etc is conserned. If I lose the plane line with the driver I also lose the ability to hole a lot of 6 foot putts. When we move on to the the greenside short game the commonalities increases. To an extent where I sometimes get a "that's it feeling" hitting a chip and am ready to rip it on the next tee with the driver.

I use minimum pivot lag when I chip. I locate the hands at the spot where they are about to overtake the shoulder turn. And I turn my torso so that the shoulders have overtaken the hips. This enables me to hit the ball pretty firm without rushing the ball over the green. It's my minimum leverage stroke. It works really well for high, soft landing chips with very little back spin and quite predictable roll. But this variationy creeps into the long game from time to time and then it's throwaway city. So the more similarities you can make work for you the better.
