What about if he uses his 26B right to forbid a spade lead and his MPC right to require a heart lead, then after cashing the Ace of hearts, he remains on lead so the forbidding of a spade lead still applies?
Any lead restriction imposed either under 26B or under 50D2a (penalty card) persists as long as the player retains the lead.
So if the HA were not a singleton, he would be required to lead another heart anyway under 50D2a. The situation you mention arises when the HA is a singleton.
Another interesting situation would be if the defender had no hearts in the first place, so the 50D2a requirement to lead a heart could not be complied with.
One might think it fussy to apply both a 26B requirement not to lead a spade at the same time as as a 50D2a requirement to lead a heart, but it can make a difference.
Sven says, fairly persuasively I think, that if you apply a 26B restriction, and it applies to the suit of the penalty card, then you have satisfied the requirements of 50D2a allowing the penalty card can be picked up. But equally if you apply a 26B restriction that couldn't be a 50D2a restriction, then the requirements allowing the penalty card to be picked up haven't been satisfied. So declarer can get two bites of the cherry, as it were, in some circumstances.
