IIUC the temporarily_switch_to_single_kboard is there so that when you
use Emacs on several terminals at the same time, interleaved events from
the various terminals is "properly" de-interleaved.
The intended use case is "several terminals on several machines with
different people on each machine".

I think a more important use case is "press <key1> on terminal1 and
<key2> on terminal2 almost at the same time and <key1> and <key2> both
expand to escape byte sequences".  So it's important that the bytes from
each terminal don't get mixed up, otherwise input-decode-map won't be
able to turn them back into <key1> and <key2>.  IIUC this use case does
not require temporarily_switch_to_single_kboard in call-interactively.
