Using \let with \csname inside a macro

Trying to understand a line in latex.ltx (regarding \string, \escapechar and \csname in the definition of \newif)

Dynamic variable name gets overwritten

\global variant of \csname…\endcsname

Indirectly defined macros: Undefined macro with "@" does not trigger compile error

Why can I not use \string to prevent the expansion of \csname?
