And you think that drawing with the unsupported remarks "explains" it?!
Note that we already have so many explanations... just take your pick! ;-)

With the half-mirror oriented like *that*?
D (detector)
S / | (mirror1)
--- (mirror2)
How silly. You have one beam directly bouncing off the
half-mirror to the detector, and one beam travelling an
extra distance of 4 times the arm length, having passed
the half-mirror twice.
Clearly you have no idea what you are talking about.
