It always happens for boolean inputs.

Try building these blocks:

define say (string1) until <boolean1>
say (string1)
wait until <boolean1 :: custom>
say []

define move while <boolean1>
forever
if <boolean1 :: custom>
move (10) steps
end

Unfortunately, the BP does not recognize boolean input blocks in custom block scripts, except in the block-defining hat, so I colored them deep purple.

// pass-by-reference implementation
when gf clicked
delete (all v) of [refs v]
set [ref_index v] to (0)

define move while (ref)
repeat until <(item (ref) of [refs v])=[false]>
move (10) steps
end

define set ref (ref) to (value)
repeat until <not<(ref_index) < (ref)>>
add [] to [refs v]
change [ref_index v] by (1)
end
replace item (ref) of [refs v] with (value)

// example usage
when gf clicked
set ref (1) to [true]
move while (1)

when gf clicked
wait (5) secs
set ref (1) to [false]

// -------------------
when you read this::events hat
say [HTH]
