SMuFL: Handbell Glyph Name Question

What is the rationale for the name of U+E816, "handbellsMalletLft" ?

On both the font specification web page and in the glyphnames.json file, it
appears as "handbellsMalletLft".

https://github.com/w3c/smufl/blob/a5692fac550b1be2d9f1cb68e2c1e5f377af0097/metadata/glyphnames.json#L4705

Is there a special reason why this glyph ends in "Lft" instead of "Lift"?
Other handbell glyphs end in "Lift":
U+E811: handbellsMartellatoLift
U+E817: handbellsPluckLift

I am not yet ready to file this as a bug report because:
1) I am not very active in the SMuFL discussions within this group, so I
may simply have overlooked a previously discussed rationale.

2) I am not an expert on handbells nor glyph names

3) Since it appears in both the web page AND glyphnames.json, this naming
choice appears deliberate. If they were different, then I would file a bug
report as a typo. However, I can't say with any certain that this is a
typo: it's just a naming convention that I currently do not understand.

If this is deliberate, I'm very curious to know why this decision was made.
If this is a typo, then I will file a bug report.

Thanks,
