For me it's evident: the symbol has left-to-right directionality for proper
use in mathematical notations, when the hebrew letter is used
orthographically with RTL direction, even if the possible glyphs of the
symbol may look exactly similar to the glyphs used for Hebrew letters. It
seems that the only apparent similarity comes from the fact that the glyph
only of the isolated Hebrew letter was borrowed in the math notation symbol.
This is confirmed by the location of the ALEF SYMBOL (U+2135) within the
"letterlike symbols".
In the chart you can see this note for U+2135..U+2138 (ALEF, BET, GIMEL,
DALET SYMBOL), which reads:
"these are left-to-rigth characters".
The LTR property is enough to justify that these symbols are not unified and
have no canonical equivalence with the RTL Hebrew actual letters. So they
are clearly distinct and effectively meant for very distinct use.
