The expression:
( $ptypeline =~ /movable.+(sine|geo|radial|ortho)/i
)[ 0 ]
is a list slice so the regular expression is in list
context but the slice is
a single value so the expression is a scalar.
The || operator will only work with scalar values,
not with lists, so this
works because the list has been converted to a
scalar with the list slice.

the list context represents everything between the / /
and the slice context represents [ 0 ] which is
assigned as a scalar to $ptypeline.
Correct?

No, $ptypeline is the string that is being searched.
