Mouse over macro issue

[Darkoon]

If by chance you go out of range of the person you are trying to heal with that macro, it will cast it on yourself instead and you will not know it until it's to late...

...If you are just using <mo> you will be unable to cast until you move close enough to be in range of the person you are healing, preventing you from accidently healing yourself instead of the tank and being none the wiser.

Bad bad macro, <mo> only.

That was not the case for me, I used the same Macro for a while but even if I was right next to the person I intended to heal, the macro would sometimes malfunction and skip both <mo> and <t>. This issue can also be experienced with DD classes where you have two or more buffs on the macro and it will skip some of the macro lines even though the buffs you intend to use are off the cooldown.
