O.K., so, you say the beam was split two ways... "so I copped exactly 50% power!"
Think about this statement carefully, let's assume the laser is giving out a stable 100mW as it hits the scanners. There were two beams being emitted from the aperture, Beam A and beam B. This translates to the scanners being in Position 1 for beam A and position 2 for beam B (you don't see light between the two beams because of the laser being blanked). Your laser is giving out 100mW, so when the beam hits the scanner at position 1 it is giving out 100mW and when the scanner moves to position 2 it's also giving out 100mW. Therefore Beam A must be 100mW and beam B must be 100mW.
What you see are two beams because of the speed of the scanners and the blanking, but the reality is there is 100mW in each of those beams.
I have to confess to being the worlds worst teacher, so that's probably as clear as mud
