Incorrect Description in tutorial "Advanced Rail signals"

I guess it should say "And also don't build a rail setup that results in the other trains having no path", but I believe a reasonable player will intuit that.

Anyway. these tutorials will probably have some rewriting done later, whomever deals with that can clear this up if it is still present
