Because you're saving and restoring the global value of
'statusline', but your InitStatusLine() function is setting a
window-local value of 'statusline', which takes precedence over the
global value.

If you need to use local values of 'statusline', you'll have to save
and restore each local value individually. If you want to restore
the statusline in a particular window to the appearance of the
global 'statusline' value, you can just clear the local value, e.g.

setlocal statusline=
