The LFO is simply outside the working range of the Phaser. Phasers are 
in principle filters - so called allpass filters. Though they seem not 
to filter the signal at all, they have a center frequency. The lowest 
possible center frequency is higher than your LFO frequency. This is the 
reason why the LFO is not shifted.

I assume it would be the same with the A-101-3.
