BFR Question

I'm a Canadian glider pilot and hold a reciprocal FAA PGL based on keeping my Cdn licence in good standing.

Every Spring, we complete a flight review for insurance purposes and currency, and the instructor puts a stamp in our logbooks that we have performed to appropriate standards.

So, does this take the place of needing a BFR? If I go to the U.S. and fly a N- aircraft, would I have to go through the time and expense of the BFR?

Since my FAA PGL is based on my valid, reviewed and current TC GPL, I would think my annual approval to be sufficient.

Anyone know the FARs well enough to inform me?

Thanks.
