Search for the term subshell.

It is quoting the ; so that the shell won't parse it.  By itself, ; is a
shell meta-character, but here, you want it to be an argument to find.
Read the find documentation for more about why -execdir requires a literal
; to end the sequence.  You could also have quoted it as '\' or "\\", but
that is more typing.
