in these reaction(Ts and Ms), why do they proceed in different mechanism/?

more specifically,

  1. (Ts) e- pair from O attacks S, (Ms)but not in latter reaction. why?

it makes no sense. because TsCl is more sterically hindered by benzene ring.

  1. in Ms, e- from hydroxyl group attack H attached to methyl group instead. I'm not famillar with H that was attached to C taken by other things. strong base can do this?

help me~
