Ok granted there could be 3 states not 2, but given our level of
uncertainty that amounts to little more than a rounding error. The state
of a synapse is certainly repeated redundantly hundreds of times in
other nearby
synapses , probably thousands, and perhaps many thousands of times; we
don't know the precise number.

To my knowledge there is no evidence that the memory encoded in LTP
depends on what chemical comes knocking on the door of a synapse.
