It doesn't, really. The equations only seem to say that
if you insist on keeping the Newtonian definitions of
momentum and kinetic energy in the context of relativity,
which is a silly thing to do when you think about it.
Physicists realised that nearly a century ago, and no
longer use the idea of a velocity-dependent mass.
