Locking Left Leg?

[Strandly]

A few weeks ago I stumbled across something that seems to have helped me a great deal.  Towards the end of a round I was fatigued and playing kinda sloppy and when addressing a ball my left leg popped into a locked straight position and I said screw it and swung away.  I ended up smoking the ball crisp and straight.  I tried it off and on several times during my next round and had similar great results.  Now I've been doing it all the time and it seems to be a genuinely good thing.

I did a internet search of locked legs when I got home from playing today and all the links seemed to refer to locking the back leg and implied it was generally a bad thing.  There didn't seem to be any mention of locking the front leg.  This makes me think I might be teaching myself something unnatural and bad.  I pretty sure I'm maintaining the locked leg (back leg stays loose) all the way through the swing but I'd need to make a video to know for sure.  Anyway, my question is... does anyone else do this?  If not then does it sound like something that would be considered bad golf posture?

No, and yes.  I can't imagine any way to get a reasonable hip turn with the forward leg "locked".

I'm trying to picture how you can maintain a straight lead leg and make a centered pivot and I can't come up with it. It would definitely restrict the amount turn you have going back.

Yeah, this one doesn't make much sense to me.
